ok so my buddy has an 89 iroc 305 tpi. when the car is cold it starts fine. after driving for a little while and the car gets hot and you shut it off, it wont start. let me clarify, it does not even crank, no clicks, no nothing. the starter relay inside next to the door is clicking and working but nothing to the starter.

now we replaced the batt, and the starter and still the same problem. I am leaning towards the starter wire from the key.... any ideas?
