Failure Date: 01/16/2008

Fuel pump/sending unit faulty. Gauge does not read proper fuel levels. One minute while going down road you have a full tank next minute light comes on fuel gauge reads empty. Sometimes gauge will not read fuel in tank at all. I have come across other GMC owners who have the same complaint. Guys at shop say it is common to replace the fuel pump/sending unit.

The fuel gauge on my 1999 GMC Sierra ext. Cab does not work. It has never worked. I did not see the problem as urgent until my brother-in-law, who has the exact same truck, got stranded in mexico because his fuel pump went out. He has had the same problem since he has had his truck and it cost him $300. 00 dollars to change the fuel pump out. That was cheap because he did the work himself. I have done some research on the internet and have seen the same problem with several trucks of the same model and year. I went to the local dealership and there is no recall on the fuel pump for my truck and would respectfully request that the fuel gauge/pump for the 1999 GMC/chevy 1500 truck be looked into for consideration for a recall.

Fuel gauge has never worked properly( jumps from 1/2 tank to empty) today I was drive on ! 40 east at the posted speed of 75 mph with 1/2 tank of fuel and the vehicle just shut down, I did get safley to the shoulder, to find I was out of fuel . . . I t read 1/2 tank previously I had heard of this happening to other GMC owners in this area but it was their fuel pumps. The dealer says it is the local refinery's falt for additvies in the fuel . . And this is the only area where the fuel system is being affected. My employeer had 2 fuel pumps put in her new GMC yukon in 6 months, at her expense. I do not want to pay for defective parts or an vehicle that is unsafe for the intersate.

I purchased this truck new, and at approximately 23,000 I was driving the vehicle at around 55mph when the engine failed. It did not sputter or knock, it just quit, all the gauges, engine quit instantly. I pulled over to the side of the road and turned the key off, and then re-started the engine. Motor started without hesitation, and I proceeded down the road. Two days later, with lots of driving time in between, the same thing happened. It died, I pulled over, turned of ignition, and re-started the motor, and again the motor started without hesitation. About two weeks later, I was driving at about the same speed and again the same thing, except this time the motor would not re-start. Vehicle was towed to the dealership, and it was determined that the fuel pump had failed. It was replaced and I had no problems until about a month ago, approximatley 05/15/2001, my vehicle started to behave in the same way. While turning left at an intersection, the vehicle died, and I was in the middle of oncoming traffice that was approaching. I re-started the engine and proceeded to get out of the way of oncoming traffic. This has occured several times over the past two months, with the most recent event occuring yesterday, 07222001, in which I was almost "t-boned" at an intersection when the engine failed. I have kept the fuel filter changed and I not use the same gas station consitantly. The fuel pump has always made a loud buzzing noise, even the first pump that was replaced at the dealership made this same noise. I understand that GMC re-designed this pump for this 1997 model. What realy got me interested in this problem, is not only the fact that I have had some close calls with almost being involved in an accident, but one of my CO-workers is having the same apparant problem with her "1997 GMC jimmy. " it has the same vortec v6 engine as my truck. The delearshipt stated they can not id the problem, unless it "runs a code, or fails while they have it. Thanks.

After fuel pump was replaced, the vehicle wouldn't start. While the vehicle was under warranty, it would not start. The fuel pump was changed but not the connector. The problem resurfaced and quit running numerous times. The service dealer stated that the fuel cap was not tight enough which caused this problem. (the cap was tightened) the vehicle stopped running while at a traffic light more than once. The consumer had taken the vehicle to the dealer and had to pay for repairs because the vehicle was then out of warranty. Several weeks later the problem recurred and the service dealer found no gas pressure and replaced the pump. The vehicle stopped again while the consumer was making a left turn. The consumer had taken upon himself to go under the vehicle and wiggled the wiring harness which started the vehicle. The service dealer changed the fuel pump connector harness. (the connector was burned and pitted).
