I recently purchased a 2001 GMC Sierra,the first tank of fuel that was put in the fuel gage jumps from full to empty, it has continued to do this until the current date, I have several people I have talked to in my area with same vehicle with different years 1999-2002, experiencing same problem, was told by mechanics that it is the fuel sending unit, have talked to people who's vehicle"s have shut down because of it, should be a recall on this problem,very unsafe!.

After driving for over 200 miles, the driver noticed that the fuel gauge failed. The vehicle jerk and vibrated. The vehicle was taken to a body shop for inspection. The mechanic informed the driver that the fuel sending unit needed to be replaced.

Fuel tank sending unit at the point where the wires connect to fuel pump are shorted to ground possibly igniting fuel vapors inside tank.

Wiring harness melted and wires shorted inside fuel tank! explosion risk.

Stopped while out of the city on the road and it would not start. Had it towed to dealership and they replaced the fuel pump.

Hello, purchased vehicle new 7/96, in 9/96 in conversation with a fleet mechanic since fuel pump is located in gas tank I was advised to not go below 3/4 tank of fuel to prevent fuel pump failuer any thing lower than 3/4 will not keep pump cool and lead to failure I followed the advise. Failure #1 occured in 1997 "original pump" dont remember exact date but dealer repaired. Failure # 2 (of the pump that replaced the first one), occurd Mar. Or may 1999 dealer replaced. Both failures resulted in total shut down. #1 occured while parked and #2 occured while driving in the city. Related issue: in June 1999 fuel filter replaced after failure. In July 99 while driving in California at hi way speeds and heavy traffic truck would temporarily shut down (no fuel no power) 6 times in a 100 mile span, resembled fuel pump again however it no longer acted up after parking for 24hours. I am scheduled to take vehicle in for search of problem next week. Excellent dealer service for repairs , and good truck, but am concearned with the fuel delivery system seems to be typical problem (fuel pump failure) with other GMC and chevy truck owners I was fortunate not to get into an accident but the potential is there, ie congested traffic etc.
