My Chevy 1991 Silverado 1500 Truck is acting up
Asked by Lamarsheat Jun 05, 2018 at 12:54 PM about the Chevrolet Silverado 1500
Question type: Maintenance & Repair
It will not move until after I let off the gas; what could be the reason why? Could
a bad fuel pressure regular be a possible cause as well?

How long since a tune-up? Any applicable trouble codes? If your check engine lite still works, you can check some codes, yourself. You use a jumper wire between A & B terminals at aldl, turn key just till the dash lites come on, then the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit code. If tbi fuel injection, 9--13 psi fuel pressure. Can you see fuel injector pulse? I don't know liter size of engine? If the engine revs in drive and it doesn't move, sounds like a tranny problem? Just my opinion.

Forgive me for the delay, but if you're still keeping an eye out of this post, my truck is a 6 cylinder, and it has been a month or two since the last tune-up.
