#1365 of 2018 Problem with 2001 S-10 Truck
Dec 07, 2005 (9:19 am)
I have a 2001 Chevy S-10 3 door pick-up truck with a 2.2L 4cly with P/S, P/B, A/C and a 5 speed manual trans. with 143000mi on it. The other day on my way home from work I picked up my truck from the park and ride lot. Vehicle started normally but when I drove up the freeway on ramp I noticed a shortage of power. The engine made a real funny noise, kind of hard to describe. Sounded kind of like when the secondaries open up on a carbureted car. But I wasn't going anywhere. Didn't overheat, didn't die when you let it go back to idle. Idled fine. But when you push on the gas and get it up to 2000rpm the rpm starts to fluctuate. Down to 1000rpm, back up to 2000rpm and so on. It makes that noise (secondaries opening on a carb car) the whole time. It will never go past 2000rpm. I changed the plugs, wires, air filter, and fuel filter. No effect. I never had any troulbe with this truck in the past! Any ideas as what could be wrong? I can't afford to take it to a mechanic right now, especially with the holidays approaching. I would appreciate any help I can get! Thanks!

One thought ... when was the last time previous to that day that went to the gas station (dis you use your your usual gas station)?? Is it possible you got a bad batch of Gas ?? There is a gas station near me that is notious for bad gas/ water in the fuel. All the locals stay away - but out of area cars get hit (as it as it's near the interstate). A Repair shop down the street makes a good living as it's only a mile or so down the road - just drops gas tanks and/or and changs the fuel ..
#1367 of 2018 S-10 Fuel pump...RESOLUTION
Dec 07, 2005 (10:44 am)
THANK YOU for all of the responses! As I said, after installing a new fuel pump, screen and ignition module we had spark and fuel flow but the engine would not start. My mechanic called one of his "buddies" who suggested checking the fuse that controls the injectors..guess what...it had blown; as designed when the fuel pump goes out! With the fuse replaced the engine started! Keep the above in mind if the same thing happens to you! (The ignition module replaced was the original when the truck rolled off the line...it had over 200K miles and 12 years of wear...not too bad!!!)
#1368 of 2018 Re: 1989 S-10 2.5 starting problems [donnydodad]

I have had a 1989 S10 2.5L for many years, now with 218K. Does the engine run normally once it finally starts or does it run rough and require extra throttle once started to keep it going? If the latter, try checking the EGR valve. It can stick open causing too much EGR making for hard starts, poor idle, or loss of power (depending on how far it is open). It can stick open intermittently, especially when hot. A scope will not show this failure (mine did not). You can also try stoking the EGR diaphragm manually by reaching under the metal shield to make sure it is not stuck. It should be closed for starting. It sounds like you have covered the basics for spark and fuel, but they could still be wrong. Have you checked for spark at the plugs yet? Does the engine seem to be too rich? Hope this helps a little.
#1369 of 2018 1995 GMC Sonoma Transmission
Dec 09, 2005 (11:16 am)
1995 Gmc Sonoma auto tranny, rebuilt and installed by shop, no problems for 12,000 miles, now it will only transmit power if the engine has just been started after sitting for a day, and then only for about 2 seconds-after this it will not shift into gear at all. Makes a noise for a few seconds when first starting engine. Engine warms up but tranny fluid stays cold. Transmission was bench tested before installation. Rest of truck drivetrain has been well maintained. Any suggestions?

I have 2, drop the pan and check for debris, or first if you have a gauge up to 300 psi check main pressure. I always do the pan drop first, that usually tells the story.
#1372 of 2018 2000 Chevy S-10 -- reliable truck?
Dec 10, 2005 (7:00 pm)
I am considering buying a 2000 S-10, allegedly with less than 40,000 miles (I am going to look at it tomorrow but will not be making a decision yet) for $8000. I would like to know what kind of problems to expect, if any. For example, I bought a used Taurus and found out later they were notorious for bad trannys. Sure enough, my tranny later went out. So I'd like feedback from S-10 owners, especially 2000 S-10 owners, as to what to expect. Thanks!

I've got a 1997 Chevrolet S10 4x4. I've recently figured out that the Transfer Case Control Module is jacked up. I simply fix it each time by putting the ignition to on then disconnect and reconnect the harness to the TCCM. I hope I can figure out why there is this flaw with the TCCMs. In my opinion GMC should fix it considering they've put this TCCM into so many models.

I have a 1997 chevrolet S10 extended cab with 4x4. Overall it is a good vehicle. I've had to replace an ABS sensor and a wiper board. Also the Transfer Case Control Module seems to have a problem which stops the 4x4 from working. I simply get it working again by turning the ignition switch on, disconnect then reconnect the harness from the TCCM and then it works again. I don't know where the flaw is coming from. Wish I knew. Something to think about though.
