I ran into the same problem and solved it. To replace the fuel pump I had to remove the bed since the fuel tank is under it. I had to disconnect the tail light wires including the ground wires. One side had 1 grounding wire and the other had 2 grounding wires. After a month of messing around with fuses and sensors I found out that one of the (Two ground wires) next to the left tail light was actually the (Fuel pump ground wire). So if you don't know which one I am talking about, make sure you connect ALL the tail light wires and plugs before cranking up the engine. This was my luck with the s10 2001 and good luck to you :)

Does the fuel pump come on for a few seconds when you first turn the key to the on position? How about the fuse? Could be the fuel pump relay.Computer or ground or wire problem.Plugged fuel filter is also possible.Did you put fuel in the tank?Stupid question but I have seen it happen.

it could need a fuel injector cleaning or replacement if an injector has a problem.check the air filter as i`v seen them so plugged to cause this type of problem.there could also be a problem with the throttle position sensor(tps)not sensing the proper voltage increase when moving the throttle.i guess you installed a new fuel pump not a used pump but sometimes even a new pump is defective and the fuel pressure and volume should be checked.it`s also possible the catalytic converter is plugging up and needs to have the exhaust back pressure checked.at idle the pressure should be less than 1lb pressure and at 2,000 rpm`s should be less then 2.how dirty was the filter when it was replaced it could need changing again if there is alot of dirt in the fuel system.

the dash sound's like a fuse, check the fuse box under the hood and in the door jamb on the side of the dash, also check your fuel filter and fuel pump, im betting on the pump because i have a 2001 chevy blazer that has had two replaced and it has 233000km on it!

1994 chevy s10 fuel problem


If you having fuel flow problem, 1st check the fuel pump make sure is has a good pressure, 2nd check the crank sensors, 3rd common problems on 2.2l injectors which it has only one can be faulty or clog. 4th check fuel regulator, if the regulator is bad it wont keep the pressure build up and lock allowing the injector to work correctly. if your fuel pump is good, your crank sensor may also be going bad, what crank sensor does it it sense the flywheel turning and it send single to ECU (computer) telling it to turn on the pump and keep it running as long as the flywheel keep turning. If pump, crank sensor,regulator and injector are good, my next guess is to have your ECU bench tested. if you have to replace ECU, get it from the junk yard.
