No start by key,but works when jumped.Help!!

Neutral safety switch? Pull it down in neutral and try it.


that was my suggestion. i had an issue with mine aswell doing this from time to time due to the trany linkage being out of adjustment and not allowing it to start unless i pulled it into neutral or poped the hood and pulled the linkage back into its correct place at the collum. though if i remember right i still had power.
