    My ATV won't start. Last year a ATV shop installed a stator same problem the ATV would not start no spark. A few weeks ago my grandson was riding and it got hot and now won't start. I have installed a new start rely ,ignition coil,and a new spark plug but no spar. I checked the off and on switch it seems to be good. Due to the battery is low I jump the ATV with my small truck engin off. It seems to be getting enough battery. The ATV just won't start. I am a single grandma wanting to take my grandson out riding this week could you help. Thank you

IT sounds like it is the pickups not working (.telling it to spark) if not then it will be CDI UNIT OR ENGINE GENERATOR COILS

Hi, Peggy you answer and cure is in the clues below and the usual suspects are:

2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Spark plugs in bad condition or partially fouled.
4. Spark plug cables in bad condition and leaking.
5. Spark plug gap too close or too wide.
6. Faulty ignition coil, module, and or sensor.
7. Loose, dirty, or corroded ignition module connector at crankcase.
8. Faulty CKP or CMP, MAP, ETS, ATS, TPS, O2 sensor.
9. Intake air leak.
10. Water, dirt, or rust in the fuel system, carburetor and/or filter.
11. Fuel tank vent system plugged or carburetor vent line closed off.
12. Vacuum line from intake manifold to fuel valve is broken, cracked, pinched, or missing.

1. #1 test. Obtain a 12 volt circuit tester, the type that looks like an ice pick with a wire coming out of the handle. With ignition on, hold the tip of the circuit test against the post of the coil, the post that is marked with a + The light in the tester should light up, meaning you have battery power. If you don't have electrical power there, trace back to battery to find out why. If you do have power at that point
2. Moving the the opposite side of the coil and place the tip of the tester again the post marked with a minus. With the key on, crank the engine. The light in the tester should flash. These 2 test have just tested your battery and ignition system. Bill
