Question about 2002 Chevrolet Suburban 2500
My truck shuts off but when I pull over and waitr a few minutes it cranks back up and rides fine. I've noticed a chevk oil pressure light came on once. I took ito to a machanic but he couldn't find anything wrond with it. Whats causing this problem?
I had the same problem with mine. I installed a fuel pressure gauge, and drove around until the problem started. The truck should be running between 48 to 56 lbs. of fuel pressure. Mine ran at idle at 42lbs. , not even high enough. Drove it for about 20 minutes, and it started to stumble. Fuel pressure dropped to 30lbs, 20 lbs - then all the way down to 2lbs. I shut it off, and it would not start back up. 30 seconds later, I turned the key and it came up to 10lbs. press. 10 more seconds 20lbs. After almost a minute, it came up to 42 lbs. started and I drove away. I replaced the fuel pump assemb. on 7/3/2008. Drove it around,and the problem is gone. Mine is a flex fuel, and the pump retails for $668.00. I did find a AC Delco pump for $221.00. I hope this helps.

I got it fix!. I had the same problem and not even the dealer could fix after several times the Suv stop running when i was driving. I took it to a mechanic and he changed someting call kill switch....he explain that when you turn off the truck there is a stich that tells the engiene to stop. He changed and and since then it works like a charm.
