I have a 2001 zx2 with 80-k. Had car since new with very little problems. lately while driving the car it shutoff all by in self and wont start. engine cranks but fails to start. check for spark and I hear the fuel pump run for a short time and stops. I tow the car home and I check the coil pack and its show good, I check the pressure at the pump and its 34-psi. try to start the car and it does. let car run for 1-hr in driveway with no problems. dealer tells me its a bad pump or coil pak any ideas.
