No fuel

[Mechanical'al]

I have a 1994 1500 suburban W/5.7 new fuel pump , relay and cam censor. the truck ran great for a few thousand miles then while driving 40 mph it quit like a switch went off. now no power to the fuel pump fuse on fire wall

Unless I am sorely mistaken... Theres no cam sensor on a 94. If everything else is working but the pump is not then I would check the oil pressure switch. I am pretty sure they supply power to the relay. At least thats what I have remember reading. I dont have a schematic for that truck to verify.
