    Have an assistant to turn on the ignition switch, while you listen to the fuel pump running for 2 seconds from the uncap fuel tank filler. No noise, take the next step.

    Try giving the bottom of the fuel tank a few whacks with a flat piece of wood or a rubber mallet while another tries to start the engine. You have a 50/50 shot at getting the pump going again and the vehicle starting. if it starts as a result of the whack then it confirms the bad fuel pump.
