Fuel pump failure by model year
What owners say
Tl* the contact owns a 2004 chevrolet trailblazer. The contact stated that there was an odor of fuel was present inside and outside the vehicle. The vehicle was taken to the dealer, who diagnosed that the fuel pump and the fuel lines were damaged which were caused by a faulty inlet check valve . The vehicle was not repaired. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 165,000.
The metallic fuel pump lines located on top of the fuel pump corroded through, leaking gas onto the ground whenever the engine was on. This vehicle has 155,000 miles on it and is now 11 years old. To qualify for the recall that was issued, the car had to be less than 10 years old or and have less than 125,000 miles. The recall period for this vehicle should be extended to include older vehicles.
On my 2004 trailblazer, my wife complained about gas fumes in the car. I noticed gas streaming from around the top of gas tank. I dropped the gas tank down and noticed the leak was streaming from one of the metal lines exiting from the fuel pump. The corrosion was so bad I only had to lightly push on the metal line and it broke into. If my wife didn't smell the fumes this could have burst into a fire if it eventually sprayed onto the exhaust system.
Bought a 2004 chevy trailblazer and fuel gauge is not working on it. Quit right after we bought it. We had also bought a 2000 chevy silverado in 2004 fuel gauge went out on it, it has the electronic sensor/sending unit built onto the fuel pump. Fuel pump works great just the sensor is broke. What is with these on the chevrolets. I have heard of others with same issue on their chevrolets.
Fuel leakage caused by corosion at fuel pump outlet pipe. Gas pumped onto ground under vehicle. Mechanic replaced sending/filter unit cost $610.00 plus 5 gallons of gas lost.
Corroded (leaking) metal elbow from the fuel pump module to the gas lines. Failure of the metal elbow caused gas to be pumped onto the top of fuel tank and surrounding areas while driving with just a hint of a gas smell inside the vehicle. The defective fuel module was replaced at an independent auto repair shop. The technician showed me the old part and where it was leaking. Corrosion was very heavy on the elbows.
I own a 2004 chevrolet trailblazer that upon trying to start sprayed gas all over the ground and my kids getting in car. I had vehicle towed to dealer just to find there was nothing they would do since I have 70,000 miles on vehicle . The dealer said the fuel pump had rusted through and needed replacing at a cost of 1,200.00$. Should a $25,000.00 american made SUV last more than 4 years???
The problem is that my 2004 chevrolet trail blazer spits up fuel back out of the fuel tank after filling up the tank. I am not trying to top off. Everytime I fill up, fuel spits back out from the tank after I remove the fuel pump. I have taken my car to the dealer twice now, they are on their third attempt to fix the problem. It happened several times before I took my car in to the dealer. I thought maybe it was the gas station I was using. So I tried several different pumps in different cities and the same thing happened. That's when I decided to take the car in for service.
I have had my vehicle for less than a month and filled it with gasoline 6 times in two cities at different gas stations. I never have topped off the tank, but when the fuel pump handle clicks off, the gasoline pours out from the tank under my vehicle. It never matters how much fuel I put in the vehicle it always "over flows."
