Sounds like your "Cold Start circuit" isn't telling the computer that the car is now warm? Two things I can think of at little to no extra costs... 1)Replace Temp. sensor/sender to the computer...NOT the sender to the guage. Inexpensive part to replace. Shop around...NAPA, Advance, etc., for best price. 2)Idle Control Valve (ICV). Clean it...may be sticking ... Read More...

FWIW... One thing I replaced once was the temp. sender to the COMPUTER.... NOT the sender to the temp. gauge/light. It was inexpensive ($10-$12? @ Autozone). Once the truck was up to temperature..the Computer temp. sensor/sender was telling the computer to not let the truck re-start. That solved my problem when the truck would not restart after getting up to ... Read More...

They ended up replacing the central port fuel injectors, now the car runs like a top! Perfect! It is the second time I have had to have that replaced, so I am worried if it will go out again. Read More...

2001 GMC Jimmy/4.3L Vortec/4X4. When I first start the Jimmy it fires right up. While driving the engine runs great,and even better now with all the new parts. I park it then try to re-start it. It only cranks and does not fire back up. I could drive it for hours,but when I stop and shut it off. It will not start back up. It will start again if I wait for 20 or 30 min. When ... Read More...
