I would first start with checking the fuel pumps. Turn the switch to the #2 position which is when the dash lights come on and listen for the hum of the fuel pumps. You should hear the fuel pumps humming and the sound will come from the rear under the car, below the passenger seat. No humming means fuel pumps may be shot . If there is a humming then fuel pumps may either be creating pressure for the injectors and the fuel filter may be clog. Or the problem could be that the fuel pumps are create pressure but not enough for injectors to fire. Also check your OVP relay. Keep us posted.
