2006 Chevrolet Trailblazer: fuel pump failure

Filed Apr 7, 2015 · Fuel system · 52,863 miles · NV

After fueling the vehicle with 12 gallons of gas, (filling it up from half a tank) the fuel gauge read empty and the out of fuel / low fuel indicator light was on. The vehicle stalled twice while in traffic driving it home, but did not result in an accident as traffic was light at the time. After calling the dealership they told me this is a common problem that happens every 50k miles "give or take" and that I need to have my fuel level sensor and fuel pump replaced. In looking online, I find that this is indeed a very common problem that has resulted in crashes and other safety issues and has been ignored by gm and the federal safety agency for several years now despite the constantly growing number of claims. The dealer stated it would cost "somewhere around $900" to have this fixed. I told them what I thought of that, bought the delphi replacement unit myself for $200 and made the repairs on my own. However gm is going to be getting a bill for this from my lawyers.

Under a previous recall the dealer replaced a part in the fuel tank and tried to sell us a fuel pump at the same time. My wife now tells me that since this service she has occasionally smelled gasoline inside the vehicle and at times quite strong. At first she thought it was the fumes from other vehicles. I do not drive this vehicle alot, so it has not been noticed by me. Is it because of a complete fill up or is it because there is a seal not installed correctly, I do not know what I do know is that under no circumstances should there be gasoline fumes inside the vehicle, which tells me that any spark of any kind could ignite those fumes.

Wife filled trailblazer with fuel during a trip today. When she returned to vehicle and started it low gas light on gauge cluster lit and fuel gauge went to zero. Vehicle was purchased at 11,000 miles and gas level has never been allowed to fall below 1/4 of a tank so as to prevent fuel pump overheating and failure, hence, this was the first time the light has been on.

My trailblazer has experienced the same problem as some other ones that I have read on here. My gas gauge quit completely, at first it would read full then go down and now it stays on empty with the light on. If there are so many trailblazers having this problem why isn't there a recall and why isn't chevrolet fixing this instead of putting it on the consumer to do it. I have ran out of gas on the highway and had to pull over and was lucky that I could maneuver it over to the side of the road. What are they waiting on for some people to get killed before they do anything about it? When it dies nothing works and you are stuck where it dies. This is a serious problem which needs to be addressed by chevrolet and they need to fix the problem, they shouldn't be putting faulty things on vehicles and not own up to it. They need to own up to the problem and fix it. Also I can't afford to have it fixed. I have been told by a mechanic that the fuel pump should be replaced not just the sensor.

1.fuel gauge on our 2006 chevrolet trailblazer ls sport with 6 cyl. Engine became erratic going up and down without relation of how much gas was in the gas tank. This started when vehicle mileage was below 40,000 miles. 2. Now the fuel gauge always reads empty, and we have to go by trip mileage to determine when to fuel up. Once june 18, 2011) when we hadn't filled the tank fully, the distance on it was misjudged and ran out of fuel on a main thoroughfare during heavy traffic. Thankfully an accident didn't happen. 3. We had checked the internet about this problem and found it wasn't rare, but quite prevalent on our vehicle and similar ones, due to defective fuel sending units having contacts corrode. We put in a bottle of gm fuel treatment, with no change. The expense to replace the combined sensor/fuel pump unit that is located in the gas tank isn't worth spending as the replacement part is identical to the original and the problem will happen again. If the fuel runs out in an intersection or rush hour traffic a crash could result that could cause injury or death..

Fuel gauge began not functioning correctly around april 15, 2011. The gauge is constantly registering empty after a fill up and then registers a half a tank and then back to empty. I have had to revert to setting my trip odometer and when I get close to 300 miles I fill up. I have check with my dealer and was told there is a fix....a new fuel sensor and fuel pump.

I am filing a complaint about my 2006 chevy trailblazer 4 x 4. After filling the fuel tank up, I returned to the car and as soon as I started the car back up, the gas gauge showed empty and the low fuel light was on. I knew this was not true as I had just filled the fuel tank. The fuel gauge will sometimes show "full" when the vehicle is in park but then drops off to empty or anywhere in between as I travel. I had talked to my local gmc dealer and they said there is a know problem with the fuel sending unit in the fuel tat send the tank level information to gauge on the instrument panel. The dealer indicated a investigation has start but no recall has been issued yet. I now have to rely on the trip odometer to gauge how far I can travel on a tank of fuel. Everytime I need fuel, I fill up all the way so a have good base line of my available mileage. This is really annoying issue. My concern is if the problem occurs with the fuel pump in the tank. If the fuel pump fails, I could be stranded some where or have a loss of power while operating the vehicle. This could be a huge safety issue that could cause a accident if the fuel pump fails.
