Why wont my 1997 GMC Sonoma start.


Asked by Jun 23, 2014 at 11:01 PM about the 1997 GMC Sonoma 2 Dr SLS Sport 4WD Standard Cab LB

Question type: Maintenance & Repair

Hi my 1997 GMC sonoma has been giving me problems. I was driving one day and then the engine shut off completely. The battery however was working fine and all lights were turning on. I got it towed home and used some Carb spray and it started so I assumed it was the fuel pump however the next day I decided to test it to see if it turned on and it did. I was able to drive it a few miles and it worked fine. Later that day the same thing happened it wouldn't start. I wanted to know what might be wrong with my truck and how I can get it fixed. Thank you for taking the time to read this about my problem I am having.

I agree with TST. Change your fuel pump. Sometimes fuel pumps just quit and other times it's a slow death. Because it would run on the carb spray tells us it's a fuel problem. HTH. -Jim


It will turn on once a day without the carb sprayer could it still be fuel pump
