    Default No power to fuel pump

    The truck is a 2002 Chevy Silverado 2500 Duramax Diesel :
    No power goes to the pump when key is turned on, fuse is fine, replaced relay looked fine but replaced it anyways. Traced the wiring and found no problems. Is there any other reason it might not be coming on? Could it be a computer problem? Thanks

    It suddenly stopped. It was low on fuel but not out of fuel. We thought it might have burned up the pump but we checked it over and it is fine. We put in a new one anyways just in case.

    Welcome to the site! That would have been my answer as well (replace fuse and relay) but I'm not sure what is next.
    Anyone else?

    Oh I just realized I didn't explain it quite right. The main problem is that no power is getting to the pump. We put a test light on the plug going into it and got nothing. So something is stopping power from getting to it.

    Try grounding out the system. Take the positive cable of the battery and hold it to the negative post for 15 seconds. This will erase the computer's memory and will either confirm or eliminate the possibility of it being an ECU issue.
