I have a 2001 sierra 2500hd that has been stalling out over the last 4 or 5 weeks. 2 times already engine cuts out and then restarts itself, and the last time it took 5 minutes to get it to start after shopping. at first i thought it was a vapor lock, so i would open up the case cap, and then it would start, but now that doesn't even help. if i have gmc run diagnostic on it, will it bring up a traceble code for the crank sensor. even though gmc is having a recall on this problem, my vin number is not encluded, the local gmc dealer said they would put it on the computer, and if it brings up this code, that gmc said they will fix it as a good well, but if not i will have to pay,

Hi diesel106, Mine was the crank sensor. It went on for about 3 years. Stalling & stopping. Shut off key & restart. No traceable codes. Then it started stalling everyday & finally a code came on. They still didn't know for sure from the code but it hasn't stalled once since replacing the crank sensor. (Sept07 to present.) I have not heard about a recall. Mine is a 2002 GMC 2500hd with the 8100 engine. If you have any info on the recall please let me know. Thanks, Stu

i found the recall on the www.nhtsa.gov gm recall no. 06083, this one is for the 2001 sierra 2500hd 8.1, i'm not sure about 2002. hope this helps, and thanks for the information, mine hasn't started stalling everyday yet, but I am hoping the times it has that there is a traceable code so they will fix it under the recall.

#29 of 138 Just Dies by highflow

I have an 03 Silverado with the 6.0l auto and recently have developed this problem. When I apply full throttle from a standing start and my speed increase passes 120kmh the truck acts like the fuel is shut off and dies. I usually have to sit on the side of the road for a few minuets before the truck will restart. No codes come up and Installed new fuel pump and filter. Does anyone have any suggestions.

#31 of 138 2003 GMC Sierra 1500 stalls frequently by drake75

Mar 18, 2008 (9:15 am)

I have a 2003 gmc sierra 1500 4wd with 4.8L engine. My truck stalls more frequently when turning at low rpms but will also stall sitting at a stop. At a stop, the truck will surge before it stalls. I have been told it could be the fuel pump but I am not sure. Any ideas?

No trouble codes? Fuel pressure is a likely cause. Hook up a pressure guage and see if the pressure drops below 55psi during the stall. Other likely causes are an extreemly dirty throttle body, or a malfunctioning idle air control valve. Start with checking the fuel pressure, Vortec's are very fuel pressure sensative. Injecters will not spray fuel unless there is at least 55psi at the rail.

#33 of 138 93 Chevy Silverado stalling by mo29

Mar 18, 2008 (3:38 pm)

I have a 93 chevy silverado and the other day was idling fine then the truck just died. I had a little trouble turning it back on. Drove fine the rest of the day. Next day drove it to work and on the corner turned off again. No warning lights come on but if you leave it off for a couple of hours truck turns on again but turns off when you drive it. Any help would be greatly appreciated.

#35 of 138 1998 2500 GMC Sierra by jumlah

Apr 09, 2008 (10:21 pm)

I have a 1998 2500 sierra that I bought used.. Automatic. 256,000K I had the rad changed and the original manifold gasket changed at the same time a few months ago. After the work was done, I noticed a hesitation in the "power band" almost like the engine was misfiring. It was very subtle and easy to miss. there is no hesitation while moving up through the gears until I hit about 90 km/hr (3rd gear), this usually corresponds to about 2000 to 2500 rpm. after that when I reach about 100 to 110 km/hr, and the RPM drops to about 2000 RPM to 2200 RPM (Overdrive) and there is another hesitation. It happens no other time. there are no Codes or check engine light. I also notice after the work was done the engine runs at a lower RPM while idling, and sometimes when I am in reverse and begin to give the engine a shot of gas it almost stall out. It did at least once.
 
I thought at first the mechanic may have messed up the timing so I brought it back. they double checked and everything was OK. They even checked injection ports and cleaned them. The problem continued, I took it to a transmission shop to see if it was a tranny problem, again no codes, the mechanic took it for a drive and was convinced that there was NOT a problem with the transmission or it's mechanical operation. The transmission was rebuilt about 76,000KM ago, and has only been on light duty. The transmission mechanic thought that it might be related to the ignition. Well, I don't know when the plugs were changed last and the truck has remote start that is no longer able to start the truck. The characteristic of the "hesitation" has not changed and continues to happen at the exact place and time while driving it.
 
I am at a loss as to what is happening. I would rather not spend ton of money trying to find the problem. Since there are no codes it is kinda hard to pinpoint. I appreciate any assistance I can get on this matter.
 
regards,
John
