Atv turns over but wont start

A car that turns over but won't start can be a real headache and leave you searching for a solution. With most vehicles, there is a specific testing algorithm that you can follow to diagnose the cause of an engine that turns over but won't start.

Here's what you need to do to find out the cause of your problem, and get your car back on the road. Make sure that you have enough gas in your car. This sounds like common sense but many people don't think to check this before wondering why their car won't start.

Try to refill your tank when it is no less than one quarter full, or you risk getting stalled or stuck somewhere. Verify that the battery has a full charge.

A battery with a low or partial charge can cause the engine to crank too slow preventing it from starting. Sometimes a jump will fix this problem, but if your battery is more than five years old you should consider replacing it, especially if winter is only a few months away. Check to see if your fuel pump is turning on. This can easily be done by putting your key in the ignition, turning it to the "on" position, and listening carefully with your ear pointed toward the back seat.

If your fuel pump is working you will here an electric "whirring" noise for about 2 seconds every time you cycle the key on and off. If you hear nothing then your fuel pump is faulty or not getting any power. Find out if the engine is getting gas to it. Sometimes a plugged fuel filter or a problem with the fuel injectors can prevent the engine from getting any gasoline.

To check this remove the air cleaner and smell inside the throttle body or air cleaner housing. If the engine is getting enough gas you should be able to sense a strong gasoline smell due to the amount of uncombusted fuel left inside the intake manifold. Determine whether the spark plugs are firing.

If there is plenty of gas but no spark, the engine will crank but not start. Unplug one of the spark plug wires and plug in a spark tester.

Posted October 15, Went out and finally managed to get my exhaust fitted to my downpipes using a gasket I made from a can of Macaroni Cheese Anyway, tried to start my bike after it and it wouldn't start, it was turning over but just wouldn't fire up, then it sounded like it was backfiring Battery got drained so I just fully charged it and same is happening - turning over but not firing up!

I thought maybe I had flooded it with petrol, how long does this usually take to clear if this is the case? I look at my fuel gauge more as a progress bar than a fuel gauge. Are you teaching it how to be a piston?

Take the spark plug out and turn the engine over for a second, that will unflood it. Clean the plug and put it back in and it should work fine.

The float bowl on the carb will be full however and will contain enough fuel to run the engine at tickover for a minute or so. Turning the engine over with the starter for a minute or so may empty the float bowl but it might cost you a new starter motor. Most probably it's fouled the plug from not running right and the fucked plug isn't igniting the stupidly rich mixture.

Why don't you navigate yourself to the back of the line with your feet and stand there with your shit.

I find giving it a minute to settle and then giving it a good bump start normally works for me.

Good point, in this situation I would normally use the massive hill next to my house to "bump" start it over about a quater of a mile of downhill. Went out to see what it was like today and it's doing the same. My brother tried to bump start it for me but it didn't go, how much speed do you need to bump it anyway? Maybe going too slow? StevenF wrote:. Weak battery and blocked air filter will cause poor starting or lack of. If the bike has been stook for a long time then the fuel might have turned blocking the carbs but i doubt that, though it might be possible.

With your poor starting you might of fouled the plugs in turn makin it hard work for yourself again. Just about to inspect the spark plugs but I can't get the tool down to reach the plugs, do I need to remove the radiator to get to them thus the side fairing as well? Most of the time, the tank and side pannels are the only things that need to be moved. Bolts are underneath the seat usually. I just unbolt the tank and turn it sideways, making sure there's enough fuel hose and that the tank is stable.

You want a proper socket like this or this for example.

My Engine Cranks but Won't Start

Obviously do check what size socket you need I brought one from Halfrauds which was deep and thin to fit down into the recess on my old ER5. The car alternative was too fat to fit. If your rating is revoked you will lose karma Have you read the ratings guide?Some issues are easy to fix at home, while others require assistance from a mechanic.

Also, if your ATV has a tether pull cord style kill switch, make sure it is connected properly. The battery should read 12,6 — 12,8V. Use a multimeter or a voltmeter to check the voltage. Am easy way to test your battery is by checking the voltage-drop with a multimeter as you try starting the bike. If your fully charged battery drops below 11,5 volts under load while you crank the starterit needs to be replaced.

If your battery is charged, but you still get nothing when turning the key, you may have a blown main fuse. Replace it with the right size fuse and try starting again.

The solenoid works as a switch that sends a high current to your starter when you push the start button or turn the key. For it to work you need to make sure it is getting power from the battery. If it does, you know it is getting power and the problem is likely with the solenoid itself or possibly the starter. Solenoid and starter issues will be covered later in the post. If you do NOT hear a clicking sound, you can use a multimeter or voltmeter to verify that the solenoid is in fact not getting power.

Look for loose or corroded terminals or shorts from damaged cables. If the plug is dry, the bike is not getting fuel and you need to continue the troubleshooting as described below. Please note that this method may cause electric shock if done incorrectly. You will find the proper steps for troubleshooting an ATV that is not getting a spark further down this post.

If the spark plug is still dry after cranking the engine for a few seconds, you know that fuel for some reason is not getting to the cylinder. Old or unstabilized gas tends to gum up over time and may create a clog. Dirt and debris getting inside the tank is another common culprit for a clogged up fuel supply.Forums New posts.

Thread starter Kat Start date Jan 6, I got back from an 8-day Christmas vacation to discover that the battery in my ninja was toast; I charged it up but it gave me one attempt at starting the bike before losing its charge. So I replaced it. Then the bike turned over just fine but wouldn't catch, even with starting fluid, and compensating for me flooding it on the first attempt turned off fuel valve, turned off choke, tried to start it with throttle held partway open - multiple attempts.

Figured while I had the gas tank off I'd clean the air filter, which disintegrated when I applied dish soap to it.

Going to pick up a new one locally here in a bit. I don't know if replacing the plugs will solve the problem. Taking off the carbs and cleaning them is outside my area of experience, and I'd pay beer to get some help with that, if possible. Tried to drain the carb bowls, but I can't get the screws to turn - one of them just won't turn; the other has stripped just enough that I can't apply any force to it. Bike has not been rained on recently or anything. M38A1 Admin.

Fuel could be the problem, but I would think it would fire and at least run rough at minimum if that were the case. Yet cleaning all the items you mentioned couldn't hurt other than if you mess something up in the process, that's just another rat trail you'll have to run down. ANY fuel will make it putter-sputter so unless there's a total lack of fuel you did check the level, right? Probably my most suspect item. That's all I got Be sure it isn't cracked or disconnected.

Do you have an inline fuel filter? Vacuum hose is intact and was connected on both ends. Otherwise I ride days a week, consistently.

Bike was running fine and sounded normal when I shut it off, so I'm going to move mechanical compression problem to the bottom of the possibility list. Once I do that, put in the new air filter, and replace the inline fuel filter, I'll give it a go again. Also, I had been spraying the starting fluid into the airbox. Which has worked before.Dan Ferrell writes about do-it-yourself car maintenance and repair. He has certifications in automation and control technology.

When your engine cranks but won't start or run, it could mean your engine is having trouble producing a spark, getting fuel, or creating compression. The most common causes are in the ignition for example, a bad ignition coil or fuel system for example, a clogged fuel filter. However, the source may also be a mechanical fault for example, a leaking valveor faulty components in other systems.

What "crank-no-start" doesn't generally mean is a problem with the starter. If the engine cranks normally, you don't have a starting problem. If it isn't cranking right the engine rotates slowly or doesn't rotate, or you hear weird noises or nothing when you try to start the enginecheck this other practical guide to troubleshooting the starting system. Whatever you do, avoid cranking the engine repeatedly with the hope that the engine will fire up.

You may drain your battery of power and damage the starter motor in the process. Instead, try to use the charge left in your battery to locate the fault. This guide will first give you six quick things you can check, and then three systems to troubleshoot—the spark, the fuel, the compression—using some simple and quick diagnostics. Then, for more help, you'll see a list of components in related systems that can be associated with a no-start condition.

To operate efficiently, an internal combustion gasoline engine needs a good spark, the right amount of fuel, and good compression a healthy mechanical condition. The lack of any of these three things will prevent your engine from starting. So, the next three sections will list series of steps to help you find out whether your engine is lacking adequate spark, is not getting enough fuel, or has too low compression.

First you want to check that a good spark is reaching the cylinders. You can do this test without a spark tester, but it's better to use one, because a weak spark as well as a missing spark can prevent your engine from starting.

If you don't see a spark, repeat the test. This time, adjust the spark tester to 30KV. If still you don't see a spark, repeat the test and set the tester to 10KV. If this time you see a spark or no spark, you have a problem in the ignition system. Consult your vehicle repair manual for your particular model for further diagnosis. Depending on your particular model, you may have a problem with an ignition coil, distributor, ignition module, igniter, or some other related component.

Other Checks You Should Do:. After checking for spark, you need to check that the engine is getting fuel. Some models, like many Ford vehicles, have a fuel pump switch inertia switchthat automatically cuts power to the fuel pump when involved in an accident. If your engine refused to start after an accident or after a vehicle struck yours in a parking lot, check for an inertia switch.

The switch helps prevent your car catching on fire if an accident occurs. Check your car owner's manual or vehicle repair manual to locate the switch.Registration is fast and you can even login with social network accounts to sync your profiles and content.

I've checked all of the following, but the it still won't start when cool. The spark plug gets saturated with gas after cranking - choke or no choke. After I warmed the head with a blowing propane heater and it did finally start and would start easily when the engine was warm.

I know somtimes when you pull it out to check the spark it will but then when it is undercompression in the chamber it won't. Bad Plug It happened a few times to friends and is always a easy try if you have one lying around.

A cold engine is harder to turn over. The only other option I can think of is that the timing is slightly off.

It is hard to say because it starts right up when warm. I am just guessing something with the spark because it looks like you have enough fuel. Wondering what he will test that I havent already done. Nothing much was wrong, but he didn't like the brass aftermarket main jet needle. He changed it back to the stock needle. He said most aftermarket needle sets were in spec. He wanted to keep it over night and check some other things in the morning after it was completely cool.

They are still trying to figure out why it starts and runs like a champ when warm, but wont try to start when the engine is the least bit cool. They don't have a clue. I know it's 15 years old, but it only has only easy miles on it. I'm going to pull the head and check for carbon build up, but I still don't understand how it starts and idles like a champ when it's warm. I believe i've got a bad ring or cylinder wall letting small amounts of oil into the combustion chamber.
