    started my truck saterday morning it ran fine for about five seconds then died. tried to start again and it turns over no sound from fuel pump. so i emptied the tank(just filled of course) changed pump put gas back in and still nothing. the only sound is from the fuel pump relay under the hood. where do i go from here? where is the fuel pump fuse (if there is one)?

    I would have to agree on this. the relays are almost as common as the fuel pump itself to be replaced. Sometimes though you can repair them if you can get it apart. Its usually just the contacts that are either burnt or rusted more than likely the latter. Good luck!!

    There is a pigtail on the fuel pump relay that you can bypass the relay. You can jump from the battery or any constant hot to the pigtail and the fuel pump should run. I would start there to confirm that the fuel pump is working and the problem is elsewhere.
