Need help!!! No fire to sparkplug

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.

What year and model is this atv? I'm assuming it's a Honda something, sinced you posted it in the Honda forum..

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