Check the fuel pressure if its within specs if okay -test the coolant temperature sensor, fuel pump relay and fuel pump and oil pressure sending unit-

Check the circuits at the fuel pump relay. Use a gage and check fuel pressure. If the pump only gets voltage through the o/p switch, it will be an extended crank. Any applicable mil codes?
