Need help!!! No fire to sparkplug

Recommended Posts

My atv broke down 4 months ago and I cranked it every other week and had no problem. Now I got every thing put back together and tried to start it and now I am not getting any fire to the spark plug . Anyone have any ideas ?

1. Make sure the engine has the correct spark plugs and they’re gapped correctly. This might seem silly, but seemingly big problems are sometimes caused by the simplest thing.

2. Check the spark plug wire condition.

3. Disconnect the main electrical connector coming out of the engine, and then check for spark again. This unhooks the kill switch, ATV ignition switch and wiring for those switches. If the spark improves, the problem is within wiring from one of those switches or a switch itself is to blame. Now you’ll need to disconnect each switch (one at a time) to trace it to the failed part.

4. Test the stator resistance. You can get the specs from a dealer or try a search online.

Dealers don’t accept returns on electrical parts, so be sure the part you order is to blame, you could be stuck with a brand new, expensive ignition part and still dont have spark. Think of your friends and riding partners who have the same or similar quad, you might be able to borrow parts from their machines to diagnose the problem.

I disconnected the electrical connector and still no spark. i do not know how to check the stator resistance. Is there a way to test the ignition coil?

Ignition coils. Measure the resistance between the primary (low-tension) wire and ground or ground terminal. It should be very low. Like .5 to 1.5 Ohms. The primary wire is the small wire going to the CDI box or points. Next measure the secondary (high-tension) wire and ground. (Note that on most bikes these days, the coil mounting bar, that passes through the coil and mounts it to the frame, is the ground for the coil primary and secondary wires.) This should be quite high, like 6000 to 13000 ohms. If the coil is out side the specs given in the shop manual the coil might be bad. Sometimes, a coil will work OK when cool but fail when it warms up. Let them cool and they work again. Also check your battery itself....

Check the stator, Standard : 50-250 ohm

disconnect the black/red wire check the resistance from the black/red wire to the ground)

( disconnect 2 piece connector and check the resistance to the ground)

Exactly what kind of machine is this? Someone may be able to get you more specific testing specs if we know exactly what you have.

You need a digital multimeter to check resistance on the stator, you need the same thing to test the coil and all the other tests that Pete suggested. Also, double check all your wiring for loose or corroded connections.

check your kill switch it may have shorted out im guessing need to know what type of bike would help.

      First time using this forum.  Owned a Kawasaki dirt bike once, had no issues.  But I picked up this 4 wheeler at an auction.  They stated it ran, but only needed a battery.  Well I do not believe that was all true.

      Some pictures are attached.  Not sure why, but the whole air filter stuff was removed.  They had some small thing inserted as a make shift air filter.

      I purchased a battery to try this all out.  Waiting to return it and get the proper size, as it was too big for the battery box.  But here is my issue I had while the battery was connected.

      1 - The lights on the steering column did not come on.  Not sure if they work or not.

      2 - The starter solenoid seems to be bad.  I have a new one on order. 

      3 - In the pick, there is another rusted part.  Not sure what that part is or what it is used for.

      4 - What is the 12v rectifier?  square bodied part.

      So when I hooked the battery up.  Pushing the start button did nothing.  Pulling the cord to try and pull start, it turned, but would never fire.  I have put in a new spark plug as well, it looked worn out.  With electric start, I crossed over the posts on the start solenoid, it turned over, but would never fire and start.

      I have read a few other threads and it stated something about needed the neutral light on.  SOmething about a kill switch.

      Any help would be appreciated.

      Hi I just got an Polaris sportsman 500 4x4 ATV the other day. I got it real cheap but I started to go into it because it didn't have compression so I bought a new piston and ring kit for it and installed it, but now when I try to start it all it does is shoot fire out the exhaust or the intake of the carburetor. And a timing is top dead center.;I think I can't really tell another way if it is or not. when I put it together I made sure to piston was on top and the cam lobes where facing down where are the cam sprocket is facing up. It has gas and spark. It did start a couple minutes ago but it didn't stay running and now it won't start. Do you think the valve need to be adjusted more to close better?I'm fixing to try that out and if that don't work what is the problem? Also I made sure everything was together good and right and change the oil and changed out the radiator fluid.
