How do you know if it's the fuel pump that went out?
Open the fuel filler door, and remove the fuel cap, and have someone turn the ignition switch on without starting the engine, while you listen at the fuel filler opening. If you hear the pump run then you at least know the fuel pump fuse and fuel pump relay are good. But that does not necessarily mean the fuel pump is pumping fuel it might just be running. The only way to verify if it is putting out the proper pressure is with a fuel pump pressure test. If you do not hear the fuel pump run for a few seconds and then shut down, check the fuse and the rely for the fuel pump. If the fuse and relay are good you know the pump is defective and needs replacing. Be sure and replace the fuel filter.
