I have power but it does nothing when i turn the key to start it. I tried to start it from the fuse box under the hood and it cranked but no start. With the key it didn't crank though.

Hi,

I suspect you jumped the starter relay to see if it would start. Have you checked the relay?

Do me a favor. Switch that relay with a different one in the box having the same part number. Or here is a link that explains how to test a relay:

Do this and let me know what you find.

Take care,
Joe

Okay, I need to know which engine you have in it. I am going to look through wiring schematics are they are all different based on the engine. In the interim, follow this link to check if there is power to the starter where we need it to be. If you have questions or need help, let me know.

Also, is there an anti-theft light on or anything other you can think of?

Let me know.
