Four Wheeler Running Then Died and Now It Will Not Start Again
This guide will help you troubleshoot the most mutual causes for an ATV that won't start. Some issues are like shooting fish in a barrel to fix at abode, while others require assistance from a mechanic.
These are the main reason why an ATV will non start:
- The ATV is not getting a spark or is only getting a weak spark
- The ATV is non getting fuel
- The ATV is not getting enough air
- The battery is bad or non charged
- The kill switch is bad or corroded
To identify what is causing your ATV'due south starting issues, you need to discover how information technology behaves when yore trying to start it. Choose the topic beneath that describes your bikes behavior best to brainstorm your troubleshooting.
The ATV won't first – the engine is not turning over
If your ATV doesn't crank at all when you lot're trying to start it, there are a few basic things to look into.
one. Make certain the impale switch/run switch is in the "ON" or "RUN" position.
You lot'd be surprised how often the solution to an ATV that won't start is forgetting to turn on the kill switch.
Besides, if your ATV has a tether pull cord style kill switch, make sure it is connected properly.
ii. Make certain the ATV is in "Park" or Neutral
Many ATVs are designed not to start when in gear as a safety precaution.
3. Make certain the bombardment is charged
The battery should read 12,6 – 12,8V. Utilise a multimeter or a voltmeter to check the voltage.
If the voltage drops also low, the battery won't have plenty charge to kickoff the bike.
Charge the battery or replace information technology if it's dead. Am easy way to examination your battery is by checking the voltage-driblet with a multimeter as you try starting the bike. If your fully charged bombardment drops below 11,5 volts under load (while you crank the starter), it needs to be replaced.
4. Check the main fuse
Most ATVs take a chief fuse. Your user transmission will assist y'all locate it.
If your battery is charged, but you still go nothing when turning the primal, y'all may have a diddled main fuse. Supercede it with the right size fuse and attempt starting again.
five. Brand sure the solenoid is getting power
The solenoid works as a switch that sends a high electric current to your starter when yous push the start button or turn the central. For it to work, you need to make sure it is getting ability from the battery.
The solenoid should make an audible "clicking" sound each time you hit the starter. If it does, you lot know information technology is getting power, and the problem is probable with the solenoid itself or possibly the starter. Solenoid and starter issues will exist covered afterwards in the post.
If y'all practise NOT hear a clicking sound, you can use a multimeter or voltmeter to verify that the solenoid is, in fact, not getting power.
- Put your multimeter to DC Voltage.
- The scarlet lead goes to the battery (red) side of the solenoid.
- The black lead goes to footing.
- You should get a voltage reading of 12V or more than.
If you don't get a reading, you need to trace the wiring back to your battery to wind where the connection is broken. Look for loose or corroded terminals or shorts from damaged cables.
The ATV won't start but turns over
A gasoline engine needs 3 essential components to start and run:
- Gasoline
- Spark
- Air (compressed)
i. Check if the bike is getting fuel
- Locate your spark plug. Yous may need to remove a few plastic covers to observe it.
- Remove the spark-plug wire (on a carbureted ATV) or the ignition coil (on a fuel-injected ATV) from the spark-plug.
- Remove the spark-plug from the cylinder head using a spark-plug removal tool.
- If the plug it's wet, yous know the wheel is getting fuel.
If the plug is dry, the bike is not getting fuel and you need to keep the troubleshooting as described below.
2. Check for spark
- Install the spark plug back into the cylinder head.
- Connect an inline spark-tester between the spark plug and the spark-plug wire/ignition coil. You tin become ane for inexpensive at most auto supply stores.
- Brand sure the run switch is in the "ON" position.
- Please keep your hands clear of the test tool and the area around it.
- Push the starter button.
- The test-light on the spark-tester will light up if at that place is a spark.
Alternative method: If you don't take a spark tester tool, yous can practice a visual test to check for spark. Delight note that this method may cause electric shock if done incorrectly.
- Remove the spark plug from the cylinder-head and connect it to the spark-plug wire or ignition curlicue.
- Take hold of the plug wire and hold the plug about ane/8th of an inch abroad from the cylinder head. Brand sure you are only touching the safety and not whatsoever metallic parts.
- Activate the starter.
- Yous should run across repetitive bright blueish spark arching from the spark plug to the cylinder head as the motor turns.
You will find the proper steps for troubleshooting an ATV that is not getting a spark further down this post.
The ATV is not getting fuel
If the spark plug is nonetheless dry afterwards cranking the engine for a few seconds, you know that fuel, for some reason, is not getting to the cylinder.
It's often either an issue with the fuel-pump or that the fuel supply line is clogged up somewhere between the gas tank and the carburetor.
Quondam or unstabilized gas tends to gum up over fourth dimension and may create a clog. Dirt and debris getting inside the tank is some other common culprit for a clogged-upwards fuel supply.
The easiest way to identify the cause is through a procedure of elimination.
Note that if y'all discover contamination such as clay or gummed-up fuel at one spot, the whole organisation is likely dirty and needs a consummate clean for the best result.
The steps involved are slightly unlike depending on whether your ATV has EFI (electronic fuel injection) or a traditional carburetor system.
Both carburated and fuel injected ATVs: Make sure the gas cap vent is not clogged
There is either a vent in the gas cap or a separate gas tank vent tube. Make sure neither is clogged and allows air to flow freely.
Fuel needs to be replaced with air as information technology gets pumped out and used. If the vent is blocked, the fuel pump may not be able to suck fuel out of the tank.
When a carbureted ATV is not getting fuel
Older ATVs, and some of the cheaper models still today are designed with a traditional carburetor fuel-organisation.
1. Make sure the fuel shut off valve is in the "ON" position
There should be a shut off valve at the lowest part of the fuel tank. Make certain it is turned on.
2. Check if the carburetor is getting fuel or not
This step volition help you narrow down the possible causes of why fuel is not reaching the cylinder.
With the fuel valve open, disconnect the fuel line from the fuel inlet of the carburetor. Plough over the engine to see if gas is coming through the fuel line.
If it is very piffling or no fuel coming from the fuel line, yous probable take either:
- A clogged upward or faulty shut-off valve.
- A chock-full-upwardly fuel filter.
- A fuel-pump trouble.
- A chock-full gas cap or gas tank vent.
If there is a steady or pulsating stream of fuel yous know that
- The fuel pump is ok.
- Fuel flows all the fashion undisrupted from the tank to the carb.
- The trouble is probable a dirty carburetor.
Continue your troubleshooting based on the results of this initial test.
3. Check if the close-off valve screen is clogged upward
Fuel exits the fuel tank through a close-off valve at the everyman function of the tank. Within this valve, a mesh screen is supposed to stop dirt and debris from entering the fuel lines.
Disconnect the fuel line from the valve to see if gas comes through. If fuel does not flow freely, yous demand to remove the valve to clean information technology.
All of the fuel left in the tank will bleed as yous remove the valve. Utilise a saucepan to collect the fuel.
Use carb cleaner, some fresh gas, and a toothbrush to make clean the valve and mesh screen. Pour some fresh gas in the tank to flush out whatsoever remaining gummed-up old fuel or droppings earlier installing the valve.
If the gas in the tank is old or contaminated, y'all should non put it back in the tank after cleaning the valve.
4. Cheque if the fuel filter is clogged upwards
Non all ATVs accept serviceable fuel filters, but some do. Trace the fuel line all the mode from the fuel tank to the carburetor. Look for a cylindrical canister unstalled in-line anywhere on the fuel line.
Fuel filters are cheap and like shooting fish in a barrel to replace, so it'due south worth doing if yous suspect that something disrupts fuel period.
5. Troubleshoot a fuel pump that is not working
ATVs with traditional carburetors usually have a vacuum-operated fuel pump. They are run past vacuum/pressure pulses created in the crankcase. The negative pressure pulls fuel in, while positive force per unit area pushes fuel out.
- Locate the pump by tracing the line coming from the gas tank.
- There are 3 rubber hoses attached to the pump.
- One is fuel coming from the gas tank.
- One is fuel exiting the pump and to the carburetor.
- One is the pulse-line (air), usually marked with a "P."
- Disconnect the inlet fuel line and position it lower than the fuel tank to make certain gas flows undisrupted from the gas tank.
- Reconnect the inlet fuel line.
- Inspect the vacuum line for any damage or cracking and replace it if necessary. Leaks will prevent the pump from working correctly.
- Make sure the pulse line is connected correctly both at the pump and by the crankcase.
- Brand sure the engine oil isn't overfilled. This may cause some oil to get trapped in the pulse-line, obstructing airflow.
- Also, inspect the fuel lines going from the fuel tank to the fuel pump. If there are any signs of conditions cracking, supervene upon the line. Cracks in the fuel line may crusade the pump to suck false air into the tube instead of gas.
- If yous take a vacuum gauge, connect it to the vacuum. The estimate should follow the pulses. If in that location is no vacuum, there may exist internal problems within the engine, like a stuck valve. Fixing such issues is usually a job for a mechanic.
If the pump is yet not working, yous may need to replace it.
Alternatively, you can pull it apart to requite it proper cleaning and a rebuild. Inside at that place are check-valves that may get suck if clay enters the pump. There is also a rubber diaphragm that may stretch or fissure over time.
6. Test a vacuum-operated close off valve (petcock valve)
Some ATVs have a vacuum-operated shut-off valve that is designed to open only when the engine is running.
Place the vacuum line that goes to one of the inlet ports. Disconnect the line and depict a vacuum to the asunder port. The valve should at present open and allow fuel to period.
Inspect the vacuum line to make certain it is correctly connected at both ends and has no cracks that will draw imitation air.
If you lot suspect that the valve is not working, put it in "prime number" as this will override the vacuum-operated valve. This will tell you if the valve is working or non.
7. Clean the carburetor
Old unstabilized fuel and debris from the gas tank may completely gum upward the carburetor or block the jets then that the engine is not getting whatsoever fuel.
I recommend using a product like Seafoam or similar to see if it will dissolve the gummed-upwardly fuel before embarking on a more than thorough cleanse. Go out the asphyxiate wide open to permit maximum catamenia.
Click this link for instructions: https://seafoamsales.com/uploads/2018/12/HOW2_Gummed-Up-Carburetor.pdf
If Seafoam doesn't work, your best bet will be to remove and disassemble the carb to clean it properly. This job may not be for everyone. Consider asking a mechanic if disassembling the carb seems intimidating.
- Start past draining the carburetor. There should exist a drain screw at the bottom of your carb bowl.
- Disconnect the carb from the ATV and move it over to a tidy workbench. You practise not want to be missing any parts when reassembling the carb.
- Disassemble the carb. Accept photos as you lot remove parts to proceed rail of where things go.
- Use carb cleaner and a toothbrush to clean as much equally you can.
- Use an air compressor with a nozzle to make clean all the pocket-size passages inside the carb.
- Remove both the primary jet and the pilot jet. Brand sure y'all can run across the light coming through information technology. If you are not able to clean the jet, information technology's best to supplant information technology. Make sure the float assembly is pulling up the float needle and is non stuck.
- Reassemble the carb and install information technology on the ATV.
- You volition also demand to address the cause for your dingy carburetor, or it volition clog up the next time yous ride. Drain or siphon all of the quondam fuel out of the gas tank. Flush the tank with some fresh gas. Supersede any fuel filters, also as they are likely but as dirty equally the carb.
- Consider calculation a cleaner product such as "Seafoam" to your start tank of gas after the cleanse. This volition deliquesce whatsoever gummed-up fuel still trapped in the system. Follow the manufacturer's instructions, depending on which cleaner product you choose to apply.
I recommend these links for a more detailed and illustrated guide on how to disassemble and clean a carburetor (external links):
How to disassemble and properly make clean a carburetor:

Clean a carburetor past using chemical carb cleaner:
When an EFI (electronic fuel injection) ATV is not getting fuel
Fuel-injected engines use an electronic pump to feed pressurized fuel through fuel injectors and into the engine.
Troubleshooting a fuel-injected ATV is a fleck trickier than carbureted ATVs, merely it's possible:
1. Make sure the internal fuel filter is not clogged
Near fuel-injected ATVs do not have a serviceable fuel filter.
Instead, they take a non-serviceable screen or a sump-filter located within the gas tank. Note that some EFI ATVs likewise have an inline external fuel filter.
The screen or filter is one component of the complete full fuel pump assembly located inside the tank. These filters are non meant to exist serviced but may still clog upwardly.
You lot need to remove the whole fuel pump assembly to access the filter.
Begin by removing whatever plastic covers to access the top of your gas tank. In that location you will detect a big plastic locking-ring that connects the entire fuel filter assembly to the fuel tank. You may need a set of large pliers to remove the band as they tend to bind.
Be careful so that y'all don't damage any fragile plastic components equally you remove the pump assembly.
The filter will exist at the very bottom of the associates. You lot will generally need to replace the whole assembly to replace the filter.
If you want to save some coin, consider looking upward a suitable replacement filter on-line.
2. How to troubleshoot an EFI fuel pump
Electric fuel pumps tend to fail for no apparent reason from time to time. Before they break completely, they may be getting weaker gradually due to wear.
A worn fuel pump may not create a high plenty fuel pressure for the injection system to mist the fuel properly, which may prevent the ATV from starting. Aftermarket fuel pumps are available for about ATVs, simply replacing them is non for everyone.
Besides, yous have possible fuel pressure regulator issues or bad o-band seals.
The best way to test an electrical fuel pump is by measuring the fuel pressure at the fuel rail. This will, however, require a specialist tool that the average habitation mechanic does not have.
A clogged fuel filter or clogged fuel lines may cause likewise low fuel pressure as-well.
Before replacing the fuel pump assembly, information technology's worth making sure the bike is charging correctly, as a depression voltage volition negatively touch fuel pump performance.
3. How to troubleshoot fuel injector problems
Modern EFI ATVs may provide an mistake code indicating fuel injector issues. Troubleshooting fuel injector issues, however, is a job that often gives even seasoned mechanics a headache. I recommend you salvage this job for a dealer.
The ATV is not getting a spark
Here are a few things to try out if your ATV is not getting a spark:
- Make sure the kill switch is turned "ON."
- Examination if the kill switch works by using a multimeter, a test light, or a elementary continuity tester. Poke one probe into each of the two cables going into the switch. There should be no continuity when the switch is off and continuity when information technology is on.
- Bank check for unplugged or damaged wires in the wire harness.
- Replace the spark plug; it may be damaged even if information technology looks ok.
- Examination the internal resistance of the ignition coil. Use a multimeter to check for internal resistance between the positive and negative final. Gear up the meter to 200. You should get a reading of 0-two ohm. Over ii ohms, the curl is likely bad and needs to be replaced.
- Test the resistance between the positive terminal of the coil and the spark plug. Set the meter to 200.000. You lot should get a reading of 10.000 – 25.000 ohms. Whatever reading exterior of this range indicates that you likely have a bad coil.
- Finally, check if the stator is working properly. You will find a method for testing the stator in this post.
The ATV won't start – information technology just backfires
When yous attempt to start the ATV, the engine seems to creepo just as normal. Merely the engine volition not start. All yous get is 1 or several loud bangs coming from the exhaust.
These bangs are known as the ATV backfiring, normally caused past the air/fuel ratio existence too rich or also lean.
ane. The ATV has get flooded
If you forget to engage the kill switch before trying to start the wheel, it volition pull gas into the carburetor, simply there is no spark to ignite the fuel.
When too much gas enters the carburetor, there won't be enough space left to mix the required air/fuel ratio for the bike to offset and run.
If you have the time, let the bike sit for a couple of hours earlier trying to start it once more.
Alternatively, y'all can remove the spark plug while turning the engine over for a few seconds. Any excess gas volition escape through the spark plug hole. Wipe the plug clean and put it back in. So try starting the ATV as usual.
two. The spark plug has gone bad
Spark plugs are considered consumables that may need replacing from fourth dimension to time. A spark plug that has gone bad may forestall the ATV from starting and only cause it to backlash.
Supervene upon the plug with a new ane co-ordinate to the manufacturer'southward specifications.
iii. The air filter is clogged
A clogged air filter will restrict airflow and, therefore, significantly impact how rich your ATV engine operates. Too trivial air will crusade an overly rich mixture, resulting in symptoms like the ones you experience.
Clean or replace the air filter with a new one before trying to start the bike again.
iv. The valve clearance is wrong
Another possible cause of these symptoms is that your valve clearance is incorrect. As the engine gets some hours to it, the valves may seat deeper in valve seats and may need adjusting.
Checking and adjusting the valve clearance on an ATV is not that difficult to learn, but it is recommended that you ask for guidance from someone more than experienced the first time you do this task. If you practice it incorrectly, you gamble causing permanent damage to your engine.
5. The timing is off
Your wheel'due south timing is what tells the bike when to pull air and fuel into the cylinder, when to ignite the fuel and when to discard exhaust gasses out the exhaust. If one cam is off by just one tooth, you may run into starting issues accompanied past the occasional backlash.
If you've been working on or removing some of the timing components, you need to brand sure that everything is reassembled correctly. Lookup a timing diagram for your specific ATV and make sure all the timing marks line upwardly.
If the job of aligning the timing marks sounds intimidating, yous are probably better off leaving the chore to a mechanic.
half dozen. The flywheel timing key is sheared
The timing might be off even if you did not work on any of the timing components. What often happens is that the timing advance fundamental, also known as a rocket key, has sheared and needs replacing.
The timing key plays a crucial role in timing your wheel'south ignition as it locks the flywheel in the correct position on the crankshaft. If information technology breaks, your bike's timing volition be off immediately.
This little metal part is designed to suspension to protect other engine components. From time to time, it may break even if at that place is nothing else wrong.
Luckily they are not that expensive or fourth dimension-consuming to supplant. Information technology is not a chore everyone volition be comfortable doing for themselves. Nevertheless, nothing an averagely skilled home-mechanic can't manage subsequently watching a couple of youtube videos for their specific brand and model.
The central is located on the crankshaft. You need to unbolt and remove both the flywheel-cover and flywheel (the flywheel on an ATV is actually chosen a generator) to access information technology. A flywheel puller may be required.
If the key is sheared, remove all pieces from the old timing key and install a new one according to factory spec. Enquire your dealer to make sure you go the right i. Install the flywheel and flywheel comprehend before trying to starting time the cycle.
Make sure the timing marks are lined up correctly. The timing marking layout will be dissimilar from model to model. Please refer to your service transmission.
7. The carburetor has become dirty
A muddy carburetor may prevent enough fuel from getting to the cylinder, causing a lean backlash.
Due to the backfire, y'all know that at least some fuel is getting through. Please refer to step 3 on how to make clean the carb.
8. The fuel is bad or contaminated (water in the gas)
Before spending coin on a mechanic, it may exist worth draining your gas tank and calculation fresh gas. Gas may go bad if it sits too long, or it may go contaminated with h2o due to condensation.
Nearly gas tanks volition take a removable drain plug or on/off switch at the bottom. Your next all-time option is to pump or siphon the fuel out of the tank.
ix. Tere is low compression
If a valve has stuck open, the compression will be too depression, and the wheel will not beginning. Repairing a stuck valve is usually a chore for a trained mechanic.
The ATV won't start – it only buzzes
If all you hear when turning the key is a buzzing sound, it is usually because your battery is dead or needs charging.
The buzzing sound y'all hear comes from the starter solenoid relay that won't kick in due to low voltage.
The solution is unremarkably quite simple. Charge the bombardment or supplant it if it is expressionless.
Also, make sure all of the power wires going from the bombardment to the solenoid are correctly connected and not corroded. Put a test light across the connexion you lot are testing as you actuate the starter.
If the problem is not battery-related, y'all may take a bad starter or even a seized engine, preventing the starter from engaging. After ruling out a bad bombardment, it's recommended to have further troubleshooting done past a mechanic.
The ATV won't commencement – information technology just clicks
When activating the starter, the engine won't plow. All you can hear is a clicking sound each fourth dimension yous press the starter button. The clicking audio is coming from the starter solenoid.
1. Bad or corroded solenoid
A solenoid that is working correctly will provide an audible click as you activate the starter. But the solenoid may be bad even if it clicks due to internal corrosion.
Utilise a multimeter to exam if the solenoid closes the circuit equally y'all attempt activating the starter.
Put your multimeter to DC Voltage. The cerise lead goes to the starter side of the solenoid. The black atomic number 82 goes to ground. There should be no reading when not pressing the starter button. But when y'all activate the starter, yous should get a voltage reading of 12V or more.
If you lot don't, your solenoid is probably bad and needs replacing.
Every bit an culling method, you lot can use a piece of cablevision to jump your solenoid. Make sure the cable y'all use tin handle the high electric current. If the ATV starts when jumping the solenoid, you know that the solenoid is bad and needs replacing.
2. The starter has gone bad
If your solenoid is expert, the problem is probable with the starter. Starters may wear out due to erstwhile age, or they may go bad from a busted seal that will let oil or water to become within of the starter.
To test the starter, you demand to remove it from the ATV. It's connected with a few bolts. Y'all will also need to remove the cable coming from the solenoid.
Apply a fully charged battery and a fix of jumper cables to test if the starter will spin equally information technology'south supposed to. First, you should use the positive lead to connect the positive battery last with the positive (red) starter cable. So attach the negative lead to the negative battery terminal.
Hold the starter firmly in place and complete the circuit by connecting the negative lead to where your starter basis to the engine.
The starter engine shaft should outset spinning freely with no signs of elevate or scraping. Supersede the starter if it is bad.
The ATV won't first later on running out of gas
After running your ATV completely dry, you lot may find that information technology won't start even subsequently filling it up with fresh gas.
If it was running fine before you ran information technology dry out, your problem is likely fuel-related as running the bike dry will not cause harm.
1. The fuel pump needs more time
The fuel pump volition need some time to suck upward fuel after the bike has run completely dry. Fuel-injected ATVs, in item, can be extra tricky.
- Brand certain the fuel tank is full.
- Turn the key to the on position, leave it for a few seconds before turning information technology off. Exercise not try to start it. Echo this process a few times, which will help prime the fuel lines and fuel filter.
- And then try running the starter for several seconds or pulling the starter rope until the bicycle starts. If the bike doesn't start afterward running the starter for about 10 – 15 seconds or pulling the starter rope 15-20 times, you should stop and continue troubleshooting.
ii. Use the carburetor primer
Not all ATVs have ane, simply if yours has a primer pump, you should use it to pump fuel back into the carb manually.
Look for a button on the side of the carb that may wait like a choke knob. You will demand to pump information technology several times for information technology to have whatsoever effect.
3. Running the ATV dry out accept acquired dirt to enter the carburetor
Switching to "Reserve" and letting the bike run completely dry may allow dirt and gummed-up fuel that has set on the bottom of your gas tank to be sucked into the carburetor.
The aforementioned applies to gas contaminated with water, which is heavier than gasoline and will autumn to the tank's bottom.
Make clean the carburetor, as described in step iii.
iv. Pour some gas in the spark plug holes
Remove the spark plugs and pour a dash of gas into the spark plug holes. Reinstall the plugs and try starting the bike.
This will provide enough fuel so that the ATV starts and begin sucking fuel on its ain. You may need to do this two-3 times earlier you succeed.
v. Blow air through the gas tank vent
Blowing with a steady pressure into the gas tank vent tube while running the starter may help the fuel to start flowing.
6. Check for a bad spark plug
Running the bike dry out won't impairment the spark plug per se, merely contaminated fuel may. You may need to replace your spark plug to get going again.
7. The fuel-pump is burnt out
Some ATV fuel pumps cant have being run dry. When run dry, the RPMs volition go up, and the pump will burn out due to a lack of cooling and lubrication from the fuel.
Try removing the pump and check for internal resistance with an ohm-meter. If at that place is no resistance, the pump is likely bad.
The ATV won't start with starter fluid
Offset of all, it is not actually recommended that you apply starter fluid on your ATV in the get-go identify. Starter fluid evaporates very easily, and the vapor is highly flammable. Both you and the ATV can catch fire from a spark caused by a brusk.
It's much safer and just as effective to carefully pour or spray some gas direct into the cylinder through the plughole. A couple of ounces should be plenty before installing the spark plugs and starting the bike.
Equally long as the spark plug provides a bright blue spark and fuel is entering the cylinder, y'all may suspect that your compression is not good enough. Use a compression gauge and bank check if the bike's compression matches manufactory spec. If information technology doesn't, the engine might need an overhaul.
If the spark seems weak, the problem may exist with the choice-upwards coil. Expect for cracks or whatsoever other visible damage. If the scroll is damaged, supplant information technology with a new one. Note that the coil may be bad even if yous're getting a spark.
The ATV won't start after washing
Most ATV manufacturers recommend that you non employ a pressure washer to clean your ATV, which may damage electrical components. Instead, it would exist best if you washed the ATV by mitt using only a garden hose and mild soap.
Here are a few tips to attempt if your ATV won't outset subsequently washing it:
- Washing may have caused grit to enter the kill switch or starter push button switch. Open the switch and clean it with an electronics cleaner.
- Water trapped inside the spark-plug booth may crusade a brusk that will foreclose the ATV from starting. Unplug the boot dry it thoroughly. Using a hairdryer volition speed upward the process.
- Leave the ATV in the sun to dry for a twenty-four hour period or ii before attempting to start it again.
- Open the airbox to bleed any water and allow the filter dry out.
- On a fuel-injected ATV, try spraying the injector with an electronic cleaner to expel any trapped moisture.
- Check if any water has entered the fuse box, causing shorts.
- Other electronics that don't similar getting moisture are the whorl pack and CDI/ECU box.
- If yous washed the bike while it was running, it might have sucked water into the carbs. Locate the drain plug on your carb and drain information technology. You may too need to replace your spark plug. But a small-scale corporeality of water may foul the plug instantly.
- If too much water has entered the cylinders from running the bike when washing information technology, it may have damaged the valves or piston rings.
- Disconnect and apply dielectric grease to every electric connector as a preventive measure for hereafter trouble-free washing!
The ATV is flooded and won't start
I've dedicated an entire post on how to repair an ATV that's been submerged in h2o.
The ATV won't start in cold weather
- Start by making certain the bombardment is good for you and fully charged. If the battery is below 12,6V, it needs a accuse to provide the necessary cranking power to start a sub-nix ATV.
- Make sure the spark plug is healthy.
- Clean the carb as described earlier in this postal service. A dirty carb may crusade issues when it's cold.
- A carbureted ATV may need a richer fuel mixture to outset in the cold. Normally, it's plenty to turn on the choke, but you may need to install ane size bigger pilot jet. Try giving information technology some gas when turning over the engine.
- The intake valves may be tight. Remove the rocker cover and make sure the valve clearance is according to spec.
The ATV won't offset with a new bombardment
You've just installed a new battery, but the ATV even so won't kickoff.
- Make certain the battery is fully charged.
- Brand sure the battery is installed correctly.
Then, refer to the other topics in this post co-ordinate to how your ATV is behaving. Does the engine turn over? Does it make clicking or buzzing sounds? Starting time from the height and work your mode down if you are not sure where to begin.
The ATV won't spring start
If you cannot jump-starting time your ATV, it may not be a dead battery that is causing your starting issues. Make certain yous are following the proper procedure for jump-starting an ATV.
The ATV won't pull start
If the ATV starts with the electric starter, it should showtime with a pull starter as-well. I recommend that you begin troubleshooting equally if the turns over but won't kickoff.
