#1 of 49 fuel pump? by mrjoesoccer Jul 11, 2007 (10:50 am)
Hello, I have a 02 Sonoma crew cab. I am wondering what signs I should be on the watch for if my fuel pump is going? would not start for a whole day, next day started fine.
#2 of 49 2001 S-10 Fuel Gauge by lbelanger Jul 12, 2007 (7:51 am)
My s-10 has started acting up and when I get to a 1/4 tank of gas it shuts down but restarts immediatly and will go another 10-15 miles and does it again. The only thing I have noticed different is my fuel gauge will go from 1/4 to empty then to full then back to 1/4. I have changed the fuel filter about 2 months ago and it was real bad then.

Replying to: lbelanger (Jul 12, 2007 7:51 am) I had a similar problem with a Tempo once before that was driving me nuts. I went through all the headaches you talked about and got the same results. Finally after several months I stumbled upon the problem. In the bottom of the gas tank are patricians that serve as a swash bulkhead. The spot welds that held them in place came loose and allowed it to slide around in the bottom of the tank. A previous involvement with a finder-bender may have brought this on. I don’t know. Any way, the Rx was another gas tank from the junkyard and problem solved. The sad part for S-10s’ is dropping the gas tank or pulling the bed off for access and inspection are a bear.

#5 of 49 2001- S-10 Fuel Gauge Erratic behavior by ken38 Jul 17, 2007 (10:25 am)
Problem #1   Sometimes when I turn the key on and start driving,although my tank has gas--either a small amount or full tank--the Fuel guage goes to empty and the fuel gauge light comes on. Then, quickly the light will go off again and on again as long as I am driving. This is happening over a month ago. Now, it is getting a little weird. the guage goes to zero, then climbs back up slowly and then to zero again and so on...   Problem#2   My ABS brake light and Seat belt light comes on while driving and goes off again off and on but nothing appears to be wrong mechanically.   ANY one had this problem who could direct me how to fix this myself or whatever?   Thanks for your help!   ken 38

Problem #1 Turn signals lights work most of the time and sometimes do not. I understand it is a manufacturer problem. Does nayone had this problem and know how to fix this?   Problem # 2   "Trac On" light and several other instrument panel lights come on and stay on for a while and then goes off. All mechanical systems seem to be working fine otherwise.   Anyone knows how to fix this problem?   Thanks for your help!
#7 of 49 Gear shifting--2001 Chevy S-10 by ken38 Aug 15, 2007 (6:19 pm)
Gear specialists;   I bought my 2001 S-10 , 4.3 liters on October 2001. Over the years I found that I had to accelerate for a long time before the transmission shifted the gears.   Quite recently, August 5, 2007 I found that the gear shifting is smoother after I changed the oil.   Boy, it is more fun to drive my s-10 now. It was a nuisance drivinig before when it was taking a longer time to shift, which i though was normal for the S10 since i bought it.   What might have caused this shifting problem?   Thanks fo yor help!   Ken 38 Replies to this message: kcram (Aug 16, 2007 5:08 pm)

#9 of 49 Fuel pump problems by bsmith26 Sep 18, 2007 (7:54 pm)
To anyone who can help me,   I had problems with the original pump about 3 months ago so i bought a new assembly unit on ebay (i know bad mistake but I'm broke) and replaced it with the new one. Well i seem to have another problem. When i get on the gas and punch it to the floor, The truck will just either bog down and backfire or just stay at the speed i gas heavy at. But when i slowly get on the accelerator it will get up to speed fine. I've changed the fuel filter to see if it could have been the problem but it still happens. Could i be looking at another bad fuel pump or is it something else?   Can someone help? Thanks, Brian My S10 is a 2000 v6 2wd vin# "W" for what its worth.

Replying to: bsmith26 (Sep 18, 2007 7:54 pm) Have your fuel pressure checked, that will rule out the ebay pump.
