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.

In february of 2012 I began to notice a very large odor of gasoline coming from the rear of the vehicle. I have owned this car since september of 2009 and this has just become and issue. Looked up vehicle recalls and came across this. Summary: on certain sport utility vehicles, a fuel filter fitting can become disconnected. If this were to occur while attempting to start the engine, a no-start condition would result and fuel would be pumped out the fuel filter onto the ground. Consequence: if the fitting becomes disconnected while the vehicle is in motion, the engine would stop due to inadequate fuel supply and cause a loss of power steering assist. If an ignition source were present, fuel leakage from a disconnected fuel filter fitting could result in a fire. Actions: dealers will replace the fuel filter quick connect retainers.

2002 gmc envoy began to emit overwhelming odors. The interior of the car and exterior of the car smells strongly of leaking fuel. The vehicle must be parked in my driveway to prevent vapors from accumulating in my garage and seeping into my home. The leaking odors into the garage and house have caused me to have severe headaches. The captured vapors in my garage presented a severe fire hazard. I took my vehicle to a local mechanic who reported to me that the fuel pump assembly on top of the fuel tank was leaking due to corrosion on several of the tubes that transport fuel. He stated this is avery common problem on the gmc envoys and that he has repaired many of them for the same problem.

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.
