Question about 1988 GMC S-15

1 Answer

88 GMC S15 starting plus other problems

These all may be related, its having a hard time starting, its harder when its warm and it takes mabey a minute of cranking while pumping the gas to get it going. It idles fine, mabey a bit high but im not sure. But when im accelerating it pluses and looses power and when i press on the gas it starts sputtering and doesnt like to go much faster than like 50 in 5th gear. Which by the way took me like 15 minutes to accelerate from like 40 to 50. Ive had this problem before but it went away for like two weeks and decided to come back. I think it might be fuel pump related.

REplace the fuel filter, then check for vaccum leakes around the intake. My guess is the carb it close to falling off! LOL Frankster016

88 gmc s15 wont stay running after it is warm


Did you check the fuel pressure before you replaced the pump ?
Can you spray carb cleaner or starting fluid into the throttle body and make the engine want to start ?
If it is throttle body injected, can you see the fuel spray when you crank it hot ?

Growling engine noise only at idle. Cam area


Take all of the belts off for a short run at idle. If the sound goes away it is pulley related, spin each pulley and listen for bearing noise, also check for play at this time.

If the noise does not go away when the motor is driving no accessories you have a more serious problem.
