How about some more information so we can see what you are looking at. Lets start with the model, type and code of the engine as well as the model number from the tag under the seat, most likely starts with 917.
Instead of just replacing parts first find your problem it might be cheaper or in the long run to have someone who knows what they doing repair it. But if you plan in doing it yourself start with bad connections. I also find a wiring diagram very handy in a repair like this. ILENGINE is right we just need more information.
