    Default Fuel pump buzzing

    I have 96 sierra 2500 7.4. It has just under 79000 original km. I noticed the other day the fuel gage stopped working. I climbed under to have a look and noticed that the fuel pump is buzzing loud enough to hear over the motor while sitting in the truck with a window open. I'm not sure if it should be doing that full time or just at start up. Does any one know why or what I should do?

    I remember always hearing mine over my engine. Could be the float on the pump that indicates fuel level, actually, that'd be the first thing I'd check

    If at first you don't succeed, chances are, you are using too small of a cheater bar
