I have a 1987 300Z she used to have a momentary contact switch in her. she wont crank or even give a click to give sign that the starter is showing life. My buddy and i were able to get the car started once today. After that she wouldnt start again we dont know what the issue is the interlock switch for the clutch was bypassed idk if there is a switch on the transmission. We have the starter relay in it now and also been following the wiring diagrams. but still can not figure out anything can yall give us some advice on where and what to look for? Its my wifes and mine only car.

 

run a hot wire down to the starter solenoid from the battery. it that triggers the starter then your problem is in the circuit that goes from the ignition switch thru the interlocks. or be sure you have power to the momentary pushbutton.

 

BAD starter !

 

ok cool well have to look at that tomorrow but i really appreciate it... i swear the guy that i bought it from was a total idiot and turned the wiring harness into a rats nest under the hood
