I smelled a strong odor of gasoline while the vehicle was parked outside my residence. Performed a walk around inspection and found no visible signs of fuel leakage. Opened the hood and had no visible signs of leakage. Envoy is hard to start but once started continues to run with no issues. Gasoline fumes are evident in the cab while parked but disperse when moving down the road. Upon stopping in traffic, fumes immediately become very strong in the cab. Researching on line similar situations, it appears that there is a problem on top of the gas tank. Checked under the envoy and noticed some minor streaking on the tank. I have stopped driving the vehicle until I can get the vehicle repaired. Assuming it is the same fuel pump erosion issue, the estimated cost to repair is between $650 and $900. Ma 10/6 the consumer stated after removing the gas tank, he attempted to remove the fuel lines from the fuel pump. The metal lines broke off at the top of the fuel pump as he attempted to remove the clips holding the lines on to the fuel pump. The top of the fuel pump and the associated metal line were rusted beyond repair. It appeared the metal lines as part of the fuel pump were spraying fuel on the top of the fuel tank when the pump was running. The design of the top of the tank with the fuel pump provided a bowl on the top of the tank where the fuel pump was located allowing salt water to pool on top of the tank during the winter driving season. The fuel pump was replaced and the tank was re-installed. Updated 03/01/16.

The fuel pump module on the vehicle began leaking. This leak ultimately lead to gasoline pouring all over the road. One quarter of a tank of fuel spilled from the tank in approximately one quarter mile. There easily could have been a fire. I ended up walking home.

2002 gmc envoy slt. Engine stalls at highway speeds. Loss of power brakes and steering. Engine will not restart for anywhere from 20 to 30 minutes. This is the 5th time that this has happened to me in the past 4 years. 4 times on the freeway and once on a surface road. This time I was with my wife and 11 month old daughter. I was not able to pull the car over to a safe location. I ended up in the left shoulder in next to the fast lane with only about a foot of space to my right where the cars were whizzing by. I cannot tell you the terror that I felt, as my daughter was in her child car seat on that side as the cars passed honking. This vehicle is very unsafe. I have read many internet postings and it appears that this problem occurs often with this make and model, yet whenever I take the vehicle to the dealership all I get is: no codes are displayed, we can't duplicate the problem, or they start throwing parts at it. So far I have replaced a fuel pump and a crank angle sensor, had the fuel injectors cleaned. The problem persists. I want to make sure that my description is clear. The engine temperature is normal, voltage is normal, outside temperature can be hot, warm or cold, it can be day or night. It has happened in all of these conditions. What is worse is that I cannot restart the engine for around 20-30 minutes, presumably there is some sort of reset on the computer ECM/PCM that occurs that grants me the right to now drive my vehicle again? This is unacceptable. My daughter, my wife or I could have been injured or even killed. I have never complained about this before except to the dealer but now that I have a baby, I am livid. I am a very experienced driver and have always been able to pull the vehicle to safety even without the power assisted brakes or steering. I very much worry about less experienced drivers such as my wife who is from a foreign country and has only been driving for two years. If she had been driving we would have.

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.

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.
