If the Car has no fuel pressure does that mean the fuel pump is bad? The fuses are good and the relay was replaced.

Question type: Maintenance & Repair

1 Answer


While you stand near the gas tank have a helper turn the ignition on but don't try to start the engine. You should be able to hear the fuel pump run a few seconds. If not the fuel pump is most likely bad. You can also hit the bottom center of the gas tank a few times with a hammer. If that gets you going it's definitely the fuel pump. Hope that helps! Jim
