#7 of 95 Gear shifting--2001 Chevy S-10 by ken38

Aug 15, 2007 (7:19 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!

#9 of 95 Fuel pump problems by bsmith26

Sep 18, 2007 (8:54 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.

Have your fuel pressure checked, that will rule out the ebay pump.

What year is your Sonoma? The pump relay on my 92 S10 is on the firewall.

i happened upon a good mechanic. who accuatlly gave me good advice. to check the relay. 2 relays located onthe fire wall to the right of brake booster. turn key on,bang on the gas tank. turn key off and repeat. no start switch the relays and repeat the previous step. mine started right up ,so i switched back relays. repeated previous steps. it started again. safe for me assume pump was bad. got new fuel pump and install turn the key nothing but the sound pump and relay dropping after releasing ingnition. pulled the pump set it in coffee can of gas and hooked a tube to the biggest line onthe tank flange ran two wires some six feet long. telephone wire works well. conennect one lead going to the pump one to black. connect other end to battery charger set on 2 amps. exstreme caution must be excersised not two create any sparks. just thought i should throw that in. turned battery charger on pump started and ran but did not pump. back to the parts store. to exchange the pump. its a new day to use up my vaction time but got to have the truck for work. will follow up on the outcome.

It is if you are getting power to the fuel pump and the ground is good. Lots of checking needs to be done before you pop for a $400 fuel pump.
