Hello, Hope you guys can help me out.
I bought a 1991 300zx NA, auto for my 16 year old son a few months ago with a partly disasembled engine. We put a used, running motor in it but it will not crank. I can jump the starter relay and make it crank but there is no power to the trigger wire at the relay. I have no experience with these type of cars. i have changed many engines in my life time but electrical problems are not my specially.
I was thinking maybe the nuetral safety switch but not sure how to test it. Also I tried removing the security box above the ECU. Thought maybe that was the issue, it wasn't. Can I just leave that out? At least now we don't have that annoying security light flashing.
Any help would be greatly appreciated, Thanks in advance.
