Cannot take off properly


Asked by Jun 01, 2019 at 03:36 PM about the 1993 GMC Sierra 1500

Question type: Maintenance & Repair

I have a 1993 GMC pickup truck and I am not
able to take off properly, when I stop at a red
light or stop sign I will press the gas halfway
to the floor/ almost all the way to the floor,
and I go at crawling speed, superslow. We
changed out the fuel pump (last night) fuel
filter and throttle body, what else could be
causing this issue

Does it have a mass air flow sensor

I'm having the same trouble


Sirkut I dont know I'll have to check but would that be a solution to fix the issue


If its extremely filthy then yes it can give your symptoms which are a fuel delivery problem.. a quick test is juat to unplug it and retest ur truck.. another option is a plugged exhaust


Thatnk you so much will be trying these out I'll lyk if it fixes the issue

We didn't check the sensor yet but after the fuel pump we filled it up with transmission fluid and a little bit of oil and it's running like a champ now Haha thanks for the help
