sounds like fuse or relay to me.. You really can't hear the pump run on mine.. when I first got the truck, the pump was going out, it whined REAL loud.. was horrible.. I replaced it, and it now is so quiet you can't hear it.. Got it from for $98, so if you need one, it's cheap enough to buy a couple.. have a spare.. Anyway, make sure the relay is clicking, by having your buddy or wife/girlfriend, random homless guy, turn the key on while you are under the hood, fuse/relay box open, listening to the fuel pump relay. small grey lower center of box. Wouldn't hurt to swap it with another relay to see if it fires up. they are cheap. check the fuse too, make sure it's good.
