2001 GMC Sierra: engine stalls while driving

Filed Apr 1, 2014 · Electrical, Engine · 86,000 miles · IA

When my issues started, I would fill my gas tank and the gas gauge would plummet to empty. While driving, it would go to full, back to empty or be anywhere in between. At that time, there no no mechanical issues, just the annoying fact that you had no idea how much fuel you actually had. This went on until this spring, when I had the first potentially dangerous incident. I was driving down a county highway at approximately the speed limit and the truck's engine just shut off. No power steering, nothing. It happened just as I was coming to a stop sign thankfully. I was about 50 miles from home and was able to call a friend that manages the collision center of a local car dealership to see about getting a tow or his opinion as to what was wrong. After about ten minutes and after numerous attempts, it restarted. I talked to several mechanics and got the same answer from all of them: the fuel pump and sending unit fail in gmc trucks around the mileage, 95,000 miles, that I currently have on the truck. The gas gauge is still erratic, I have had two episodes of the vehicle stalling and now the service engine soon light is coming on and when it is put on an analyzer it says emissions, but there is nothing wrong with the emissions system. I have also talked to owners who have had theirs replaced and everyone says to get a factory made pump because the cheap aftermarkets break down even quicker. I googled the information and the problem appears to be widespread.

Tl*the contact owns a 2001 gmc sierra. While driving approximately 15 MPH on normal road conditions, the engine stalled. All of the warning indicators illuminated on the instrument panel. The engine immediately restarted without assistance and the vehicle began to operate normally. The service engine warning indicator remained lit until the engine was turned off. The vehicle was taken to an authorized dealer for inspection and they stated that the failure was related to the crankshaft position sensor. Through research, the contact discovered the federal safety agency campaign id number 07v521000 (engine and engine cooling). He was informed that the VIN was excluded from the recall, although the failures were identical. The vehicle has not been repaired. The failure mileage was 50,000 and current mileage was 65,000.

I dont really know what lead up to the failure but the pass lock anti theft system on the gm products really needs to be looked into. This problem can cause the vehicle to shut down at any given moment or not start at all. 90 % off the vehicles that have the pass lock system on them have problems. Gm mechanics say it is the ignition switch or this or that but it isnt it is the passlock system. After parts have been replaced it still happens. I live in a small rural community with alot of trains and I dont feel that my truck should be stalling on the railroad tracks because of this problem. After looking around on the net to find help there is thousands of people who have this same problem. What happens if the vehicle stalls in the wrong place or an emergency comes up and it will not start. Someone could get seriously hurt or even killed. I beleive this is a serious safety issue and should be looked into. My vehicle itself stalled for 10 min in the middle of the road. I really dont know what could fix the problem except there is ways to bypass it. Rewire your ignition switch. This could cause other problems. Or you can buy a fifty dollar bypass module. Then you have to live with the security light on. Ya you could unplug the light in the message center but what about all the other alerts that come up in there. You would loose them. I would rather have my security system working properly so that if someone trys to steal my vehicle they have a harder time doing so & so my family and I dont have to worry about stalling somewhere. I would think that with all the complaints that gm gets about this they would have a bit of an idea to fix it. Thank you for your time

The safty defect is that the engine just quits at any speed. The same problem happened two times. Once at 3793 miles on april 5, 2001 and then again at 6340 miles on may 15, 2001. Both times the engine began to ping and then just stopped running. Both situations happened while on a major highway at highway speeds. I was lucky enough to be able to get to a shoulder lane on the highways. The safety problem is if the truck should stop at a location where road repairs are in progress and the shoulder lanes are blocked by cement barriers to not allow me to get off of the highway lanes with heavy truck traffic. This is not hypothetical, I drive hwy 35 between san antonio and dallas and the highway is allways under repair, the cement barriers are up and the heavy truck traffic is there. The disaster waiting to happen is the truck stalling at these locations.
