Three problems related to fuel pump have been reported for the 1997 GMC Yukon. The most recently reported issues are listed below.
At 250,000 km. Oem fuel on 97 GMC Yukon quite. Oct 2007 purchased a carter fuel sending unit which gave up Jan/2008 at less than 5000 km. Of service during cold weather. Returned for warranty and install new unit Feb 2008 which gave many starting misses and hesitations and finally left stranded during minus 30 celsius weather Dec 2008. Carter fuel pumps tested first unit and said pump runs fine so you will pay for second unit. Neither unit runs consistently without being rapped on a time or two during a trip to town. Yes I had to make a special floor access to the tank as the towing fees would have been astronomical not to mention the repair bills. The second unit lasted 10,000 km as it was warm weather. Reminded purchased oemgmc unit which performs flawlessly in this minus 30 weather.
The consumer stated three years ago she had to replace the fuel pump. The fuel pump has been replaced five times in the last three years. The second time the pump was replaced the wires were burned. The wires were replaced. Gm told her to take the vehicle to a gm dealership and they would pay for the fuel pump, but not the labor.
Electronic fuel pump is getting hot and overheating, causing vehicle to stop running. Dealer's solution is to keep vehicle full of gas, or replace fuel pump with the same design pump. Defect can result in fire or accident.
