Have a helper turn on the ignition switch without starting the engine, while you listen at the fuel filler door with the door open cap off. The fuel pump will run for a few seconds and then shut down. If you hear nothing then the pump is bad or the fuse is blown or fuel pump relay is defective. Even if you hear the pump that does not mean it is actually pumping fuel. A fuel pressure test is the only way to know for sure if the pump is actually pumping fuel with the correct pressure. First thing to do is replace the fuel filter if the pump is running and the car will not start.
