Chevy S10/GMC S15-Sonoma: Problems & Solutions

    I posted an earlier message concerning this - so take a look/search. In summary - for about 15 - ~ $19 PER vehicle you can get access to a LOT of the schematics, diagrams, TSB's, recalls, etc., etc. Go to and go the the DIY section ...

    Good Luck !!

    try the relays. There are usually two on the firewall for the fuel pump. If the relay is bad the fuel pump will not engage. You msut replace both relays when you replace them. You can see if they are the problem by jumping them. You can take a wire and put it from one pin to another and it should engage the fuel pump. Without seeing your relays I couldn't tell you which pins though.

    also trouble shoot the relays. They may be bad and are preventing the fuel pump from engaging.

    My 95 S10 2.2 will start nicely and idle rather bad, But when i accelerate it starts running really rough and will not accelerate then it will completely shut down making a roaring sound.I noticed the back fuel injector is leaking gas...Can someone help me with this

    Youre problem lies most likley in youre computer. 99+ vortecs used VATS wich makes the truck not start without the correct key. Change youre computer to a 96-97 computer and I bet it starts. You can also have the computer reprogrammed but it costs 300$ or more. You can get a cheap computer from a local junkyard for around 100-200.

    hey, i recently bought an '03 s10 with 5k miles. i go to college in rochester ny, and was wondering how the brakes on the ls 2wd are in the winter. i always assumed the truck had discs in the front and drums in the back, but i'm not sure, i don't have the truck here right now. and if they do have drums, are there any conversions i can buy for the back? how are they in the snow? thx.

    It runs good at idle for about 10 minutes then reves up high - then dies. Won't start for a couple hours afterward. Code 12 blinks always... reset it and tried again, just blinks 12, nothing else. Sounded like it may be sucking air but can't find a pin hole anywhere. Any other suggestions? Has new wires, plugs, distributer, throttlebody, fuel filter, fuel pickup, oil level is fine, ???? can't figure it out especially with the codes coming back as 12 all the time.

    Thanks again!
  • I have a 97 S-10 2.2 and am also having fuel lick from the back fuel injector. I went and got a new injecter and it filled my cylender up with fuel and started licking fuel from the exauste. We pulled it apart and found the new injecter was staying open and sending fuel into the air intake. Do you have any ideas as to what I need to do or what I can do.

    You will need to get a spring compressor for the door hinge spring and then you can pound the pins out the top goes in from the bottom and the bottom goes in from the top

    Hey I just recently purchased a 1998 S10 ZR2 with 54,000 miles on it, The first weekend I owned it I went mudding! This past weekend I went fishing, I took my truck out on the bench, I pushed the button and it blinked but it didn't engage, I have been looking it over and I can not figure out why it wont engage. I know its all electrical, and vaccum and what not. If anyone has had this problem please inform me! I have had nothing but bad luck with this truck.

    I have 2003 Sonoma ZR2 Extended Cab with slight grinding from behind dash. Only in low RPM sitting in drive. Did you solve your problem? please email back what the problem was and how to fix it.
    Thanks Don

    Check out message #647 on page 33. I think that's the same problem . I had that problem too, although I think the dealer fixed it 40000 miles ago and it went away, but it's doing it again occasionally. Perhaps its time for a new valve again...
