Okay, my friend has a 1992 GMC Suburban and for the past few months it's been having fuel problems. If you accelerate to high speeds it would putter and you have to slam on the pedal for it to stop. Today i was borrowing it and went to get on the high way and it puttered then died....wont start back up at all

HI. You might try doing a fuel pressure test on it ,sounds like you have a dirty fuel filter or fuel pump is going bad. good luck Slim :screwy:

you may be barking up the wrong tree with the fuel idea...that problem could also be caused by faulty ignition components. Almost sounds like an ignitions module or pick-up. Just my :2cents:

Good luck with it.
