1994 gmc Sonoma 2.2 - Fuel issues (hard start and stalling while driving)

15

Asked by lifeisahoot86 Aug 21, 2020 at 02:40 PM about the 1994 GMC Sonoma 2 Dr SL Standard Cab SB

Question type: Maintenance & Repair

I just bought the truck 2 months ago, it would take about 10 seconds before
the truck would start. last month a brake line pinched and leaked gas all over
so i dropped the tank to repair the fuel line. The fuel pump is brand new but it
had a bad ground. once the tank was back on it wouldn't start at all so i had
rigged a relay so the pump would start as soon as the key was turned. when
i got it back from the mechanic (got a tune-up and rebuild of the exhaust
system) it was back to starting after 10 seconds. last week it stalled while
driving. the next day i couldn't drive more than 3 minutes without it stalling
and it would take at least 5 minutes before starting again....now it won't start
at all.
My dad had this issue with his saturn which was just a bad ignition control
module so i changed that but no luck.
i bought a pressure gauge so i'm going to try that and try to do the relay wire
again until i can figure out what the actual cause is. aside from this the truck
runs amazingly!!!!!

update: I did a wire bypass yesterday and it started right up. Its a temporary fix but it'll do for now. I did notice that the relay was not getting power to the grey wire, so it might just be an electrical issue but i am replacing the oil pressure / fuel pump sensor today.
