Hey guys, I have a 1975 280z and I just rebuilt the engine, Had it running smooth for about a month, parked it the other day and now when I try to start it, it dies in a couple seconds, cant get it to run any longer than that.
However if I unplug the Cylinder Head Temperature Sensor, I can keep the car running if I push on the throttle. If I let the car warm up by doing this it can idle by itself for a good couple minutes before dying.
Sensor is new with the rebuilt engine and connections all read correctly for resistance. Is my sensor bad? Or do I need to check other things? Fuel pressure regulator? Please help.
