Asked by Feb 22, 2015 at 02:19 AM about the 1995 GMC Jimmy 4 Dr SLE 4WD SUV

Question type: Maintenance & Repair

My car won't accelerate normally. I push on
the gas peddle and the car will go but the
acceleration won't pick up. If I go peddle to
the metal the car will stall out. However,
this only happens once gas is under 3/4
tank.

99 Chevrolet Silverado 4x4 the truck was hot wired by previous owner and the steering wheel column has been replaced. It was running and cranking now it will turn over but won't start. Any ideas as to what this is?

95 GMC might need a fuel pump

99 Chevy you need to check for fuel pressure and spark, both can be an issue, if you have fuel pressure and spark, check for codes .
