Eight problems related to fuel pump have been reported for the 2002 GMC Envoy. The most recently reported issues are listed below.
Tl the contact owns a 2002 GMC Envoy. The contact stated that while operating the vehicle, an odor of fuel was present inside and outside of the vehicle. Also at times, fuel was seen on the pavement underneath the vehicle. The vehicle was taken to an independent mechanic who diagnosed the vehicle and stated that the fuel pump connection line was defective and needed to be replaced. The vehicle was not yet repaired. The local dealer and manufacturer were not notified of the failure. The failure mileage was 173,000. Invalid VIN.
The contact owns a 2002 GMC Envoy. The contact was driving approximately 60 mph, the engine stalled with the illumination of the low oil pressure warning indicator. The vehicle restated and resumed normally. The vehicle was taken to an authorized dealer who informed there was a faulty power train control module. There was a recall associated with NHTSA campaign id number 04v829000 (engine and engine cooling). The VIN was not included in the recall. The vehicle was repaired. The vehicle was taken back to the dealer for the similar failure. The technician was in the process of replacing the fuel pump. The failure mileage was approximately 125,000.
We have a 2002 GMC Envoy with approx 77,000 miles, the truck has strong scent of fuel in the garage and out doors. I understand that the fuel pump module corrodes and is common problem on these vehicles. I believe that gm should cover this under recall could have serious fire. I believe it is an engineering defect.
Noticed the smell of gas. Took to dealer where purchased. Fuel pump was fine, but the tube had corroded. Extended warranty purchased will not cover this because the pump did not fail. Failure was due to corrosion. The vehicle is only 5 years old! cost estimate is over $600. 00 to fix. Have to replace pump also. When repaired, I will ask for the old part. This vehicle has been in shop for repairs more than any one I have ever owned. (front wheel bearings went at about the same time, but were covered under the warranty).
2002 GMC Envoy fuel smell. Took to 2 different gm dealers before problem was found. The 2nd gm dealer found it to be the fuel pump module which was rusted and leaking gas. Gm would not stand behind this problem as she was the second owner. The problem is the way metal fuel pump module sits in the recessed portion middle of the plastic fuel tank invites moisture, rust , salt, corrosion etc. Replaced at our expense of $520. 00 this is a design problem.
Gas smell both in and out of vehicle. Within a couple of days gas would leak after car was driven. Fuel pump leaked due to rusted pipe on fuel pump to fuel line. It is the only exposed steel fitting and sits on top of the gas tank where water and moisture can collect, which is then conducive to rusting.
The GMC Envoy XLT experiences a total loss of power under the following conditions. When the fuel tank is at or below a quarter tank of gas the vehicle's gas pedal becomes inoperable and the forward velocity is lost to the point that if you are in traffic the vehicle will immediately began to slow down resulting in a completely hazardous and unsafe situation where the driver has no choice but to pull off the road or be rear ended. This has occurred on several occasions only under the conditions described above. Several GMC Envoy XLT owners have expressed the same situation. This has been reported to GMC in 2005 but it appears that the problem is known but they aren't accepting responsibility as a manufacturer. Possible indicators may be the fuel pump assembly, fuel pressure regulator, or some other vital componet in the fuel system. I am sure gm knows.
Was driving at 65 mph on highway. Depressed accelerator and vehicle did not accelerate. Went to pull over and noticed there was no power steering or power brakes. Motor had stalled. The vehicle behind me nearly collided with me as I could not maintain speed and I had to swerve amongst traffic to get to break down lane. Tried to re-start in breakdown lane and incident repeated within 100 yds. Vehicle was towed to GMC dealer for service. Dealer had vehicle fail at least 3 times on roadway under same conditions over a period of 4 days. Dealer diagnosed failure of fuel pump module (pump, sensor, filter). Parts are being replaced today. After an internet search, I learned this is a "common issue" with this model vehicle. Should be a recall or preventive maintenance bulletin.
