Question about 1988 Chevrolet S-10

2 Answers

Truck cut off, there was no gas going to carburator.

My truck cranks up but won't stay cranked. I put in new fuel pump, now something is blowing the fuse. I can hear the pump work for about 1 minute, then fuse blows. What could be causing this new problem?

A shorted relay can cause this also a wire rubbed through from when fuel pump was installed. check for cracked wire insulation.

Hey there..my name is Keith..and the norm is..if something blows a fuse..its a powered item...such as a wire..or an electrical componant that has brushes..or a relay that is a direct short to ground..so if you ran your truck out of gas..and the fuel pump was starving..and drew amps..it could have burnt up your fuel pump relay..and its shorted internally..so not being there to check it out..that would be my guess..if not..i would suspect a chaffed wire to the fuel pump..but they are usually covered in a wire chase/conduit..i hope this helps..if not..write back...Keith

GMC 2000 sierra pick up 1500 sounds like it wants to start but won't turn over. Battery sounds good so I guess battery and alternator are ok. For several years fuel gauge doesn't work and...


It sure could be. But, first...by "won't turn over" you do mean it cranks at normal speed but won't start?
A simple test of the fuel pump is to stand by tank and listen as someone turns key to on. When first turned to on, your pump will activate for 2 or 3 seconds, pressurizing the fuel system, and then shut off if the engine computer doesn't get a cranking signal. Do you hear it come on? If not, then something's not turning your pump on. If you can hear it buzz on briefly, then maybe it's your filter. Another test: Spray a little starting fluid into your intake manifold (remove the big hose going into intake manifold) while someone tries starting it.If it doesn't fire and try to stay running, then it's probably an ignition problem. But if it does fire off, then you know it's a fuel problem-likely your pump or filter. good luck.

Gas not getting to the carburator. Starter turns


Check all of the fuel lines very carefully for breaks or cracks in the fuel lines, especially between the fuel tank and the fuel pump.

If the fuel lines are all in good condition then you can safely assume that the problem is in the fuel pump and you will need to replace it. (If the fuel pump is in really bad shape the engine oil on the end of the engine oil dip-stick will smell like fuel)

Escalade won't start


check the fuel pump. there is an access port on the fuel rail underneath the intake manifold cover. it looks like a valve for putting air in a tire. at your local car parts store you can find a fuel pressure guage to make sure your getting the 45lbs psi that is needed to run the fuel system. if your not getting 45psi when you crank the engine replace the fuel pump. it is located in the gas tank. ( FYI ) If you run below a 1/4 tank of fuel the fuel pump is no longer covered with gas, and over heats. thats why most of the gm pumps go bad. D

Truck won't stay running


if it is a electric fuel pump take the fuel line off carburator and get a three foot gas line hook it up to the gas line on the car run gas line into an empty gallon container and turn key on and see if you are getting a good flow of gas
