The fuel filter is located along the frame rail on the driver's side. You might check the fuel line connections to the fuel filter. Probably a good opportunity to just replace the filter anyway.

No surprise the problem is with the fuel pump replacement (as opposed to being a problem in the dashboard). I'd tell the garage that replaced the fuel pump that the fuel guage isn't working now and see what they suggest.

ok, ill start with some backround information, have a 94 gmc jimmy with the vortec engine, have had the car for a while now and never had a problem with it until this point, recently the car quit on my brother while driving, towed to a garage and left the keys in the glovebox for repair, the next day they called me and said it ran fine, and they couldnt get it to not run......, so i picked it up, brought it home brother took it to work drove it home, few hours later i tried to start it and nothing it just turned over, bought a fuel pressure gauge and its running 60 psi turn key engine off, but just cranks and cranks and cranks, today i bought a new coil and installed, the car sat roughly 1 hour inbeetween starting attempts and installation of the new coil engine started i let it run roughly 20 seconds turned it off and tried again and back to the same old problem just turned over, as i installed the coil the only thing that changed was i was moving around the wires that run from the distributor cap to the coil, and or the power source, pulled a spark plug and had no spark, moved around the coil (wasnt bolted down yet) and got a spark but the engine still diddnt turn over i shocked my dad so i stopped trying lol, just wondering if anyone has a clue whats happening with my truck, im figuring its a short somewhere in the ignition, but dont know where to begin to look, i would appreciate any and all advice thanx guys

check the 2 wire harness connector on the pump side,on top of fuel tank. you can reach it from directly behind left drive tire. make sure both wire connectors are tight within connector itself. the rubber grommets also need to be snug. it is recommended to change that specific harness pig tail,when changing pump. if you check fuel pressure at rear of engine,using proper pressure guage. fuel pressure has to be minimum 58 psi,while cranking,or it will not start. your pressure regulator may be at fault and not the fuel pump

check crank position sensor and wiring. it will not allow engine to start, if it cannot read crank position and will not give (CEL), check engine light
