1999 Chevrolet Tahoe Owner Comments

Fuel pump went out on 1999 Tahoe. Took to dealer to service under extended warranty. I was told that there is a service bulletin about the wiring harness with a warning that they can be faulty and short out the fuel pump, in which case the new fuel pump would not be covered under warranty unless the wiring harness was replaced. I was also told that there is a recall coming out on this very problem but only for 2000-2003 (or 2004?) Tahoe. My concern is that if this is a know problem that happen to thousands upon thousands of 1999 Tahoe why aren't the 1999 Tahoe being included in the recall that is soon to be released? I was told this by my dealer.

Regarding your defect investigation peo4042 fuel system, gasoline delivery, fuel pump, 2000 - 2001 Chevrolet Suburban: Complaint that fuel pump wiring overheats, resulting in engine stall and fuel leakage from the top of the tank: Fyi, this is a common problem with all 1996 and newer Chevrolet / GMC gasoline engine trucks, all of which have the vortec engine series. This engine requires high fuel pump pressure (55 - 60 psi), which requires high electrical current for the pump, particularly under conditions of high fuel demand, such as towing (the circuit has a 20 amp fuse). Possible root causes of the problem may be: (1) inadequate wire gauge to the pump, causing a voltage drop and consequently high current draw; (2) high resistance at the fuel pump connector; (3) restricted fuel filter; (4) running the tank low on fuel; (5) increased frictional drag in the pump with high mileage. Unfortunately, there is no recommended "fix" other than to change the fuel filter often, keep the tank over 1/2 full, and replace the fuel pump every 30,000 miles ($600 repair at a GM dealer). I became aware of the problem when the fuel pump fuse blew in my 1999 Tahoe at 33,000 miles, stranding us in a remote part of Montana. The cause was shorted wires at the fuel pump, requiring replacement of the pump. A search of the Chevy truck owner's website (google) will show many owner complaints and suggested fixes for the problem.

Fuel pump failed on the highway, causing the vehicle to stop without warning. Mileage was only 33,100 at the time. I have searched a Chevrolet truck owners website (google alt.trucks.Chevy - advanced search: Fuel pump) and found many reports of fuel pump and/or fuel pump fuse failure in 1996-2001 Chevy trucks. The typical failure seems to be melting of wires inside the pump, causing internal shorting, which was the failure in my vehicle. Failures were reported typically at 30,000-75,000 miles. Failure can be intermittant and difficult to diagnose. An additional cause of fuel pump fuse blowing is shorting of the oil pressure switch, which is in the fuel pump circuit. Repair was covered under my GM extended warranty, but would have otherwise cost approximately $700.
