I have a Lumina 96 minivan it will not start. We have changed the fuel pump and the fuel pump relay and fuses but it still will not start. We have figured out thier is no power going to the pump but we have power to the float. We have a remote car starter. Could the car starter be the possible cause for it not starting? or should I be looking somewhere else. The van is turning over good and will fire if gas is added. Any help would be greatly appreciated.
