Fuel odor -strong, from region of fuel tank. Loss of fuel while driving, far more than normal useage! Investigation shows faulty tank to fill line connection at tank 'spout'. Or fault at fuel pump area- hidden on top of tank. Parked strong gas odor. Driving or on grade, fuel loss !

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.
I could smell gas and my son a mechanic looked at it and said it is leaking on the two lines that come out the top of the fuel pump.
Ignition switch failure at speed causing loss of power to fuel pump which ultimately meant loss of power to vehicle at freeway speeds. Was told by gm that there is no recall on this particular ignition switch at this time.

- What is wrong
- 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.
- Risk
- 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.
- Remedy
- Dealers will replace the fuel filter quick connect retainers. Owner notification began september 20, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1‑800‑222‑1020.
