How do you check if fuel pump is working in vt commodore?

Open the fuel filler door and remove the gas cap. Listen at the fuel filler opening while a helper turns the ignition on but does not start the engine. The pump will run for a few seconds and then shut off. If you do not hear the pump check the fuel pump fuse and the fuel pump relay. If they are good then the pump is more than likely defective. If you hear the pump then you know it is running but that does not mean it is pumping fuel. A fuel pressure test will verify the condition of the pump. Be sure and replace the fuel filter.
