Filed Jul 26, 2008 · Fuel system · 49,000 miles · VA

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.

Dt*: the contact stated there were two problems with the vehicle. First, the fuel gauge worked intermittently, but the vehicle has not been inspected by the service dealer concerning this issue. There were no warning indicators prior to the intermittent failure of the fuel gauge. Second, the passenger window dropped into the door without warning. The vehicle was inspected by the contact and it was discovered a cable was broken that held the window in place. A shim was added to keep the window in stationary position.

While on a trip gas gauge malfunctioned. The fuel gauge remained on 3/4 while the mileage was 335. When filling the tank it showed full after 4 gallons were delivered. The problem continued thereafter till present. The only way to know the fuel level is by the tripometer and guess work.
