It would help a lot if you post what you did to test it so far.

Obvious questions come to my mind: do you have a key ? Does On/Off switch is on ? Is it a pull start or electric start ? If electric does it have good battery charge ? Did you check coils etc. ?

The more information you give us the better the chances to find a solution in a short time.

thanks for the response,

it has both electric start and pull rope. has good

compression and battery is good. when i first got this

atv it wouldnt idle.. it sat all winter. then found time

to work on it and now it doesnt have spark.

checked all grounds and connections.

thanks

I'm no expert but logic says if it was running before, it should now. Electronics don't go bad from sitting unless there has been a short sometimes. I assume you already checked all the safety switches. I have a Polaris Sportsman and I cannot start it if I don't have the key, to bypass this I have to disconnect key switch and put a jumper wire in harness then use safety switch to shut off.

Can this be your case ?

when i turn on the key the nuetral light come on,

kill switch in the run position.

this thing has me stumped.
