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.

2002 Chevy Tahoe. Around 3 years ago the 1st


If a vehicle shuts off while driving down the road. then restarts after about 10 minutes, its a bad crank sensor or the wiring to the sensor. A check engine light may not turn on. If the light is on. You can take it to any auto parts store to have the code read by a scanner for free. Auto-zone, Advanced ETC. Its worth a try! But first check the fuel pump relay, It may be getting hot and shutting down pump. Try swapping a relay of the same type, if it is ok, thats the problem. Hope this helps!

My 2002 Chevy Suburban will start but not stay running and the Remote locks sudenly do not work either what could the problem be?


Without more information, it's impossible to be sure, but it sounds like your security system module has failed, and it is in "lockout" mode, where it will shut the fuel pump off after a few seconds in order to disable the vehicle (thinking it's being stolen).

98 Suburban will not start


Check for spark when it won't start. If no spark, it's an ignition problem-suspect the crank position sensor. The computer won't cause spark from the coils if the crank sensor gets hot and fails.

Check the thermostat and the fan too. Overheating nothing to do with the heater core, even if you shut the heat off, the car should not overheat

does it shut off then after 5 minutes while cooling down will it start up again then run a few miles then shut off again. if so it is your crank sensor. if your vehicle shuts off while driving and you give it some gas and it boggs out it could be your fuel pump or filter.

Engine shutting down in extreme heat


Mine does the same thing as far as shutting down on long trips---usually 1 1/2 - 2 hours. I don't think it's overheating....it's got something to do with antitheft system
