    I have a 1998 GMC SIERRA Z71. When I turn over the ignition just before I start it I here a semi loud almost buzzing sound. It stays on while I am driving, It turns off a couple of seconds after I turn off the truck. Is this the fuel pump? It seems to be coming from under the truck near the gas tank?

    They usualy quiet down after it warms up. They seem to be louder when it cold out-side.

    That's what I noticed it does quiet down later in the day when its warm. Any of you guys know of a good cat-back system with the side sweep. I've used flowmaster in the past but I want to give something new a try.
    Thanks Jerrid
