I have been rebuilding my 77 280z for about a year now and while repairing the engine and dash wiring harnesses found that my car wouldn't start. I did a harness swap with a 78 280z because the old harness was toast in the engine. I dont know where to start looking for problems. I know it isnt the coil, or the brain, I have been working on the realys and think that might be a possibility, any ideas?
