ive been dealing with this problem for months now...replaced almost everything...fuel pump, spider injector(which was conversion to multiport), fuel filter, aif filter, spark plugs(twice) spark wires, distributo cap and rotor as well as distributor itself, alternator, battery, ignition coil, map sensor, catalytic convertor, but the truck still wants to buck and cut out when cruising on highway and either going uphill and putting it under a load...or just when i pass a car and come off the gas...does it one day, then not the next, then does it for a week straight, then it goes off....only thing is one day when i shimmied the main harness that runs across the intake plenum it kinda got better for a day or two....did it again and i got no help....im about two steps away from driving it over a cliff i need some help!!!

| I took my S-10 to three shops (Chevy dealer was the last one). Bottom line is that the fuel pump was not holding pressure while driving. I bought an "original equipment" fuel pump online and had the first shop install it. That resolved the problem. NOTE: Don't skimp on the replacement fuel pump - the off brand ones go bad within a few months. Good info from the mechanic. | |

Had my truck just stall while driving on the road. First thing I though of was maybe a fuel problem, changed the filter and still no luck. Did not think of it at first but realized the fuel pump was not kicking on, also found the battery was drained down. Took the alternator and had it checked and found it was charging at 17 V. Also found the ECM fuse was blown. Changed the fuse and the alternator and the truck started right up, ran for about 3 min and shut right off again. The ECM fuse keeps blowing. Replaced the Fuel pump relay and still no luck. When you turn the key on it instantly blows the ECM fuse. Take the fuel pump relay apart and the fuse does not blow, but naturally the truck won't start. Also just for the sake of spending money to help the economy, I replaced the ECM. Help!!!!!!!! Doc

| I have also done everything I could think of but still the truck will idle fine but won't move when driving. Fuel pump checked ok, new fuel filter, new air filter, spark plugs, spark wires, distributor cap and rotor. Truck still wants to buck and cut out when cruising going uphill and putting it under a load. Has anyone had any luck with cleaning up the injector contacts under the manifold cover or by replacing the PCM? | |
