When the car will not start, check for fuel pressure at fuel rail if that is good then the pump is functioning properly and you should then check for spark. If you have low or no fuel pressure check for voltage at fuel pump, if you have none then check the relay and switch. If you have voltage but no fuel pressure makesure the connector is tight on the pump, or that the pump is good.
