#214 of 242 s10 runs rough threw gears unless i gun it.HELP!!
Mar 04, 2012 (7:10 pm)
Ok, I have a chevy 2000 s10 2.2. Engine was rebuilt a couple years ago and has 40,000 miles on rebuild. Its idles fine and cranks fine. When its cold it seems to run ok but when it gets warm and you start off from a stop the engine will start to bog down,skip,jump,pop and backfire but if I push the peddle to the floor it will straighten out and run. It seems to happen around the 2500 to3500 rpm mark. It is a 5 speed so it is hard to drive. As long as the rpm,s are high it doesnt happen. Sometimes it runs great no problems what so ever. I have replaced feul pump and filter. Air fiter and tried varios types of injector cleaner and run several gallons of race fuel threw it. The mechanics dont seem to know whats wrong with it and just want to replace this and that and I cant afford that. Anyone have any ideas.. Thanks

Every time the outside temperature is above 75 and the humidity is up, the truck runs very rough. Sometimes, when I put it in gear and press the pedal, it won't move. Just sits there and sputters. When it does run, enough to get me home, I can floor the pedal and it will just sputter and pop and slow down to a crawl until I let off the pedal and depress it gingerly. We've replaced just about everything but nothing will solve the problem. Even the GMC dealership couldn't do it. They told me to have the catalytic converter cut out.
#216 of 242 Chevy s10. Stalls often, when not accelerating

So I just bought this s10 for 800$ with 168kmiles on it the oil was leaking bad, I have that problem fixed but now when I drive it when ever its idling it's weak, there are pauses in the idle. When ever I come to a stop or take my foot off the acceloration it dies. Most every time, any got some ideas on this old hunk of metal
#217 of 242 stalling S10, fuel pump?
Apr 16, 2012 (2:13 pm)
My 2003 S10 has been giving me issues when i get near a half a tank of gas. It's quit on me on the highway, as far as I can recall always on in incline. Today it started with this with 3/4 of a tank of gas. If I roll to a decline and turn the key, it starts right up. Originally i thought the fuel gage might have been the problem, but when I add gas, its consistent with what the gage shows. I would think if the fuel pump was toast that it just wouldn't start, but i read something a couple of weeks ago that suggested they can get "weak" Any opinions?

If the pump assembly is like the ones on the 95 model, I'd bet that the hose connections in the tank that goes from the pump to your fuel line is either loose or cracked or something to the effect that it's sucking air when it's not submerged in the fuel. That would explain your half-tank dying issue, especially on an incline.
My problem was a weak fuel pump on my 95 that after driving a few miles, would drop in pressure, eventually stalling out the vehicle. It would idle all day long but when pressing the accellerator, would slowly decrease pressure while driving. I would pull over and it would start immediately and run for another 2 or 3 miles then die again, sounding like it ran out of fuel. I put an in-line pressure gage, between the fuel filter and engine with a long enough hose so I could duct tape the gage to the drivers window and monitor the pressure as I drove. I could see the pressure drop off and eventually get to zero when it would die. Idling was fine with full 30 or so PSI of pressure but when the engine demanded fuel during accelleration, it would drop off. Weak fuel pump.
I would make sure your connections in the tank are good first of all and if they are good where you are sure it's not sucking air from inside the tank, I'd change the pump. A GM mechanic told me that those pumps need to stay cooler than most by keeping at least a half tank of fuel in it to help the pump from heating up and prematurely dying before it's time.
I crawled under the truck and pulled the bed bolts (6 each), disconnected the fuel spout from the bed and just slid the bed out of the way to gain access to the top of the fuel tank so I wouldn't have to drain the fuel and drop the tank to work on the pump. Not a very hard job for a tinkerer like me.

After searcing for answer to this problem myself. IT'S THE COIL!!!!!! I put in a 400 fuel pump, fuel filter and $400 cat converter and the problem was a $35 part!!!! Runs like a dream!
My Chevy s100 2001 acted like it was out of gas. It would die while going down the road. I could put it in N and it would start back up. It started getting worse but bucking and stalling when turning corners. Finally it would go about 5 miles and die and just wouldn't start. I had top mechanics looking for the problem and an OLD shade tree mechanic fixed it in 5 minutes! The coil is locted right on top.

I have a 1999 Chevy S 10 V6 that my father gave me with 80,000 miles on it, The truck sat for 6 months.It starts fine but once it warms up the engine runs very rough, It uses a lot of gas.. I have had it to the mechanic, had a tune up, I changed the mass air flow sensor but still the same..any ideas ? I have had great luck with this forum with my Ford Diesel, Any input would be appreciated!!

There has been issues with fuel hoses leaking under the intake plenum, not sure yours has them, check it out. 4 cyl man myself.
