Question about 2002 GMC Sierra
I've got a 2002 Sierra 8.1 SLT. The truck dies about three times a day. No code ,No check engine light. It has a new fuel pump and filter. So I know that's not the prob. I've narrowed it down a bit. If It dies I just open the air box and 90% of the time it starts back up. If that dosn't work I have to disconnect the pos cable and it will start back up. I have cleaned up the MAS sensor and put a new air filter in it but it dosn't make a differance. Any thoughts?
I have the same problem with mine, and after some time i decided to clean the carberator and it started right up... No more problems..
