Chevy s10 1996 here and a very similar problem. Pepboys charged me $160 to tell me that something was wrong, but they didn't know what it was. Thats what I told them when I walked in there and then they charged me for it? LOL
 
Bought it in September when it was still mostly warm. The rain doesn't seem to cause it to not start, but as soon as it got cold it started having issues. Its automatic and I'm more used to driving manual, but once its started at least I know that it need more gas to keep it started. It shimmies and shakes until I get it moving, then maybe 100yards later it evens out. Three seperate mechanics think I'm nuts cause it always starts when they try it. Automatic is started just by turning the key right? I shouldn't have to pump the gas to get it started right?

I have read of similar problems. It was cause by carbon collecting on the intake valves and absorbing the fuel on cold start, sorta like no choke.
I thought I would throw this out for you to mull over.

I mention this to my mechanic and then I also mention that on the way home today I slowed down to make a turn and though I had lights I had suddenly lost all other power and the engine had stopped. No warnings, like sputtering, or misfiring sounds, just suddenly wasn't there.
 
From that he was now pretty sure it was the trucks computer, and when I told him that the first time we did a engine diagnostic the fuse that let the computers talk was missing, he became certain that it was the computer. I had bought the truck used and we now figure that the dealer or prior own just fudged things to make it sell able. And since the seller did some work on it before I took it home, we think it was him because apparently some of the issues Ive had were noticeable to anyone that knew what an engine was supposed to be like. er that meant not me.
 
I'll let you know how the computer change goes. =)

Well on the power loss. That truck is known for ignition switch failure, not the key one but the electrical switch at the lower column.

1999 Chevy S-10 PU 4.3 ltr. engine, won't start when wet, once it dries out and the weather clears it will start. We've replaced cap, rotor, plugs, fuel pump and fuel injectors. Check engine code of P0300 (random misfire). Can anyone help this is getting very frustrating!

#60 of 314 mystery no-start by dennis36

Dec 26, 2007 (6:11 pm)

Hi I'm new to this forum and have a real mystery here. I own a 2003 S10 pickup bought new.It has 27000 miles. Three times in past 2 weeks I experienced a no start that seemed all the world like a low battery. Had truck towed home and replaced battery,still would not start. It sounded more like older GM cars that had jumped timing. Let it sit overnight and it fired up in morning. Took it to a very reputable garage in my area,they could replicate problem or suggest any fix.Took it home and drove for a week,and it happened again.Truck had been driven about half an hr and parked. About 1 hr later it would not start,same as before slow hard cranking, volt meter shows better than 12 volts,Let it sit for 5 hrs and fired right up.Been driving it for a week now,and it did it again.Did notice a small drain on battery when hooking up neg batt cable dont know if some drain is normal or not. Anyone got a suggestion

#61 of 314 cold starting problems by adam6479

Dec 27, 2007 (2:24 pm)

I have a 2000 s 10 zr2 with 129000. If the truck has sat for more than 24 hours in the cold it wont start. It turns over fine, it has fuel pressure, i can smell unburned fuel from the exhaust pipe. I'll try to start it for a few days with no luck. Then it will fire right up on the first try some three days later with no effort other than turning the key. If i drive it every day it is perfectly fine. After i get it started it is fine. The cap, wires and plugs and about 2 years old.

#62 of 314 S-10 will not crank by awh_1957

Dec 31, 2007 (7:13 am)

I have a 1998 Chevy S-10. I killed it and went to restart it. I turned on my key and it would not turn over. My dash instrument lights will not come on, nor will my fuel pump engage. My headlights and dome light as well as radio and horn will function. I put a brand new battery on it and still nothing. Any help will be appreciated.

#63 of 314 2000 sonoma will not crank over by mongoruss

Jan 04, 2008 (5:34 pm)

Ok, I have V6 in my 2000gmc sonoma that will not crank when attempting to start. The dash lights up, under the dash clicks(normal sounds) are there, under the fuse box relays click as well but no sound at all coming from solenoid or starter. This happened twice before in recent weeks, after long attempts at jump starting it did start like nothing was wrong, however this third time it will not crank. I replaced the battery, no fix. I really believe its a bad +battery cable, there is more than one wire on the + side so its possible, the one looks bad and I am going to replace it...Also, where is the starter on the v6 4.3.any help at all would be appreciated
