HI,

I am sorry that you have not been helped yet. I just came online and saw your question.

Ok, I need to know the vin number to pull the schematics, but the first place to start is checking the starter for 12v at the small wire at the solenoid when turning the key to crank when it wont start. If 12v is present, then replace the starter as it has a dead spot. If 12v not present, we will go from there.
