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

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
