I have a 77 280z with an 82 ZXT swap 82 engine harness haven't run the car in a while. Now I start the car it will run idle for about 60 seconds or so and then shut off, things are clicking under the hood I think its Injectors but fuel pump doesn't seem to be running. Acts like something is killing ignition as well as fuel pump. After a few mins with the key still in the run position, I can hear the fuel pump start up again but can't start the car. I then turn off the key wait an hour and the car will start and do the same thing again.
Any ideas?
Thanks
