#123 of 168 99 chevy S-10 engine cuts out by bethsman Oct 13, 2008 (3:24 pm)
I have a 99 chevy S-10 with the 2.2 engine, manual trans. and 135K miles. My problems started about 2 weeks ago, when driving at a steady speed if I try to accelerate the engine tries to die. The best way I can describe it is, if you press the brakes to stop and don’t press the clutch that jerking motion the vehicle makes, it happens for a second then everything goes back to normal. Except for 2 times it did something different. One of the times I was in fifth gear and went to accelerate nothing happened (engine did not bog down or speed up). The gas pedal was all the way down to the floor after about 45 seconds the truck sped up. Then the other day I was making a right hand turn and all my lights dimmed and the oil gauge on the dash went to zero, my battery gauge went to about 9 I lost power steering. I thought my truck had stalled but the engine was still running and sounded really bogged down. After a minute of coasting the truck went back to normal and ran good the est of the way home. I have not drove it since. The plugs, wires are good. replaced the fuel filter, got gas from a different station but it did not help. I’m lost on what the problem is. I have been told it could be the fuel pump, short circuit, cam shaft position sensor, timing chain, injectors, or the computer. I'm getting no check engine lights. If you could give me any help it would be greatly appreciated. Thanks again for your help. Replies to this message: peterhailey (Oct 14, 2008 6:50 pm)

Replying to: bethsman (Oct 13, 2008 3:24 pm) anyone having an electrical problem on a chev s10 should read this. This actually happened to me. While crossing the burnside bridge my engine started cutting out. then the amp meter and speedometer went wacky. Then the fuel gauge went haywire, oil pressure fell to zero. I almost didn't make it home. A diode had gone out in the alternator. With everything being electronic these days the computer wasn't receiving info from the sensors. 2 years later while driving down the freeway the engine suddenly quit. I knew it was electrical. After a few minutes I found the problem. The negitive terminal on the battery had vibrated loose. Thats right! every eletronic system in the truck fails all at once with just one screw loose. If this were a military vehicle GM would be buying back everyone sold as new defective.

Replying to: mptimko (Mar 06, 2008 5:04 am) Hey I was wondering if you ever got this resolved. I have the same exact truck and it's doing the same thing. I can't figure it out. Can you please let me know what you did to fix this problem. Thanks.

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!!!

Replying to: drew5385 (Dec 08, 2008 3:37 pm) almost forgot, MIL kicks on sometimes when it hesitates, codes is a po452 evap emissions, and when it gets bad i get a bunch of codes like tp sensor and map sensor, which i have already replaced both of those too.....

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.

Replying to: mthompson1 (Sep 13, 2008 6:42 am) I'm having the same problem but hasn't thrown that code. Have you ever found the problem? Replies to this message: hayman1 (Dec 17, 2008 1:37 pm)

Replying to: hayman1 (Dec 15, 2008 4:18 pm) I found the problem the small rubber line between the pump and line in the tank ruptured.

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!!!!!!!!

Replying to: doc15 (Jan 03, 2009 6:26 am) As you know that fuse is also for the fuel pump. Disconnect the fuel pump at the tank, if it still blows, check the fuel pump wiring for a short to ground.
