I have a 1992 gmc Sonoma 4.3 vin z, I ran out of gas put gas it started just fine 3 times stoped filled tank, drive 1.2 miles it died , and won't start, replaced fuel pump , checked all fuses


Test for spark at the plugs and post back. Also, spray a little carb cleaner into throttle body and then try to start it to see if it is a fuel issue.

1996 GMC Sonoma Acceleration problem!


If the check engine light is on I would have that checked first. The trouble codes in the computer will help point you in the right direction for troubleshooting.
You could have a sticking fuel injector, or an ignition problem, or both.

I have a 2002 GMC Yukon xl, every time you give gas it dies, and then wont start for a lil while, what can this be


Could be low on fuel pressure, or a problem with the throttle position sensor. But if the sensor was faulty you should have a trouble code in the computer and the check engine light should be on.

1988 GMC C1500 pick up won't take more than 1/4 throttle. I punched out the catalitic converter and it still wont run at full power. I"ve had the throttle body gasket replaced as well, with no results....


I would not only put ANOTHER new fuel filter on, bot I would also be concerned about WHAT IS IN THE GAS TANK ? besdes fuel, and is the FUEL FRESH ? Hope this Helps .
