1990 Ford Tempo 4cyl. It starts as soon as you turn the key. Then dies instantly. What could it be?

All the fluids are full. Changed plugs, wires, and the cap & rotor. Has new thermostat. It just wont stay running.

Did you check the fuel pressure?

I would make sure you have power to the positive side of the coil with the key on. It may be an ignition switch failure too.

Will it run if you hold gas pedal down? Could be IAC idle valve problem. Check TPS too.
