2001 GMC Sierra Electrical system Problems

“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. …”

“Truck will run fine until warm. Pulling into stop sign, garage, traffic light,parking lot etc. Truck will shut off. Alternator gauge pulls down below 9 volts. New alt. Belt, new alternator, new fuel filter were replaced. Several bottles of injector cleaner were used over a six month period. Nothing helped so far. I have had several near accidents due to this. The last one was on a divided highway when I stopped at a stop sign and the engine stoped and I ended up out into the south obund lanes of traffic. Luckily nothing was coming.”

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. …”

“Failure of ABS module caused ABS light and red service brake lights to come on. Replacing both front hub bearings (including both front ABS sensors and wiring) and repairing the ground strap on the frame for the ABS system did not fix the problem. Service brake system has new calipers ,rotors,and pads and a full inspection revealed no problems or failures. Abs module is still on vehicle but will be replaced next.”

“Dt: the consumer took vehicle to the dealership for manufacturer's recall 05500 work on 7-28-05 for the ignition distributor system. It was inspected and replaced. . When the consumer took the truck to dealer it was running well, there were no problems. About 30-45 minutes later consumer was called by the service desk and informed that truck needed a new distributor. However, consume r did not believe that truck needed a new distributor. …”
