Fuel Pump problems of the 2006 Chevrolet Trailblazer

Fuel gauge displays empty when filled, then works sporadically, mostly not at all, highly unreliable. Dealership says fuel sending unit, and possibly fuel pump.

Gas gauge does not operate has a reuslt of defective fuel pump.

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,ooo 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 defetive 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. .

1. On 5/19/2011, after filling my 2006 Chevrolet Trailblazer with gasoline, I noticed the gas light had iluminated on when pulling out of the station parking lot. I drove down the road two-three miles before pulling over and letting the car sit for 20-30 minutes. Upon restarting the engine, the gauge moved to 1/4 tank, and then dropped back to empty. I drove home, and upon starting the engine the next morning the gas gauge was still showing empty. After 2 days, the gauge moved back up to 3/4 tank. On 6/1/2011, I had 1/4 tank and refilled, only to find the gas light illuminated a second time after fueling. The gauge is currently reading 3/4 tank when just filled yesterday. 2. In response to incorrect gasoline gauge in my Trailblazer, I have begun paying close attention to miles driven and resetting my odometer at each fill-up. However this is only a quick-fix, as I forsee issues arising due to inablitly to properly read gasoline levels in my tank. 3. At this point, I have made a phone call to the dealer, estimated repari exceeds 1,000 usd. No action has been taken at this point to replace the fuel pump/gauge. Thank you. Rochele r. Locey.

Fuel gauge failing to register correct amount of fuel. Took to local mechanic and they said the fuel sensor has failed and need to replace entire fuel pump system. Quoted repair cost of $900 (including parts and labor).

Faulty fuel gauge / fuel sending unit / fuel reading / fuel pump. I have had to have my fuel pump replaced three times now due to faulty fuel sending units. This is a major problem because my truck now shows that I am always on empty and can be a huge hazard and life endangerment. I dont want to be going down a highway at 70 mph and have my truck stall. I have replaced this unit twice already and I am now with a faulty one again. All original manufacturer equipment. No after market replacements. It seems that new manufacturer units will work for about 10,000 - 30,000 miles and then fail. This is an issue that I have seen reported hundreds of times by gm owners of Trailblazers and similar makes. My problem is with a 2006 chevy Trailblazer v6 LS model with 126,000 miles.

I started having problems with the fuel gauge swinging between full and empty then my check engine light came on. I've been told that I need an whole new fuel pump assembly and that the fuel tank will have to be dropped to replace it. I've been just setting the trip meter and filling it up every 250 miles because the fuel gauge now just stays lit on empty all the time. I don't have any problems with it running, starting, etc. So I'm assuming that it's just the sensor that is out. 2006 Chevrolet Trailblazer ext.

I have replaced the fuel guage,fuel pump on my 2005 Trailblazer after it quit working. I also have a 2006 Trailblazer and my wife ran out of gas, when we filled it up, the gas guage did the same thing as the 2005, so we have to use the odometer to know when to fill up. When I called my mechanic, he explained the situation was the same as my 2005. This is a very expensive repair.

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 pullover 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.

We own a 2006 Chevrolet Trailblazer. The driver added fuel to the tank; however, the gas gauge indicated that it was empty. The driver turned the vehicle off and back on to see if the gauge would reset; to no avail. The following day the gas gauge did indicate that the fuel tank was full; yet, while driving approximately 25 mph, the gauge slowly began to move up and down but never indicating that the tank was full. Since the fuel gage has malfunctioned, the contact is unsure of how much fuel was in the tank. The engine shut off a month ago because the fuel tank was empty and the fuel gauge did not indicate that. The driver did contact a mechanic who stated that they needed to replace the fuel pump. A mechanic stated that the failure was common for Trailblazers and the it would cost between $600-$1200. To repair the vehicle. The failure mileage was 70,000 and the current mileage is approx. 76,000.

Like thousands of other owners (since this happens to the GMC envoy too, so it's not just a chevy issue), one day the gas gauge works fine, the next it reads empty after filling it up. However, as a bonus, the friendly check engine light now comes on randomly to let me know the fuel gauge isn't working. I've had the codes read by two different places and this is the only error recorded. I now have to use the trip meter to "guess" when the truck needs filling up. Since it's going to cost me several hundred dollars I don't have to fix it, I'll just have to live with the inconvenience. In massachusetts, like many other states, they do an emissions test by plugging into the vehicle's computer. Well, since the check engine light has come on at some point, the computer says "not ready" and the vehicle fails the test. You have to wait until the light goes off and then drive about a week before the computer resets itself. However, without fail, the light always comes back on just before taking it back to get re-inspected, thus resetting the whole process. I've had this happen for the last 3 weeks in a row regardless of number of days/miles driven. Another week and another tank of gas wasted. So, in order to get the car to pass inspection, I either have to get real lucky with the check engine light or have the repair made. Since this issue prevents the vehicle from passing the state inspection, it should be considered a safety/emissions concern and all vehicles recalled to repair the combination fuel pump/sending unit. If gm doesn't consider this a concern and recall the vehicles for this repair, then they need to have the vehicles recalled to have the check engine light stop coming on so the vehicles can pass state inspections.

I have an 06 chevy Trailblazer that the fuel gauge is not reading right. I have been told that I will need a new fuel sensor but to get that I will have to replace the whole fuel pump. I have done some resource online and have seen that alot of people are having the same problem. We all seem to feel that gm should do a recall for this part.

The contact owns a 2006 Chevrolet Trailblazer. The contact stated that the fuel gauge was defective and as a result, she was unable to tell the level of fuel in the vehicle. The vehicle was taken to the dealer who diagnosed that the fuel sensor and fuel pump needed to be replaced at a cost of $ 600. 00. The manufacturer was made aware of the failure who offered to pay for half of the repair costs. The vehicle was not repaired. The failure mileage was 90,000 and the current mileage was 108,000. Updated 06/26/12 the consumer stated she ran out of gas twice. Updated 06/27/11.

At around 80,000 miles my 2006 cheverolet Trailblazer started showing empty when I filled up with gas. Now at about 85,000 miles it continually shows empty. Have researched and found out that I will have to replace the whole fuel pump/intake and outtake which could cost around $800 at the dealership. Have also found out that this is a common problem with the later model Trailblazers. Needs a recall!!.

Fuel pump sending unit gas tank shows empty even when the tank is full was told it would be 700. 00 to fix this should be a recall the Trailblazer only has 48,000 mile son it.

When I fill my gas tank the fuel gauge goes to empty and stays there, and sometimes goes erratic up and down so you never know how much fuel is in the tank. I am very afraid that by not knowing how much gas is in the tank, it may lead to over filling and causing a fire hazard at the pump by spewing gas all over to running out of gas in a passing lane of a highway possibly causing serious injury to myself or anyone else in my 2006 Trailblazer, to injury or death to anyone in their car that may hit me or run into someone else to avoid me. This is an extremely dangerous situation that I see occurs to many, many others with my 2006 gm Trailblazer similar models of different years!! at this time I have not gotten to a mechanic on this issue, but seeing on blogs it appears to be the sensing unit and fuel pump.

Own a 2006 Chevrolet trail blazer. Have run out of gas three times because the gas gauge does not read. The car is full of gas, but the gauge still reads empty. Have run out of gas on main roads and caused traffic jams. Will cost over $1000 to repair the fuel pump.

2006 chevy Trailblazer: after filling the car up, the gas gauge reads empty and throws the check engine light. I have been told this is not an uncommon problem. It has also been brought to my attention that it is caused by the fuel level sensor/ fuel pump assembly. I was also told that it can cause problems with the drive train if it is not fixed. I have spoke to other Trailblazer owners and they too have the same problem. My Trailblazer only has a little over 43,000 miles on it.

First of all my fuel lever sensor went out. I only figured it out when I was in a busy shopping intersection and my vehicle just shut down. Lucky for me no car rear ended me but one did come close. At the time as far I knew my car had over half a tank of gas in it. Come to find out late it didn't. To my embarrassment I slowed and stopped traffic for close to an hour while I called for help and had to be towed. My mechanic explained the problem (the fuel level sensor) and gave me two options get the part replace or keep track of the mileage and gas I put in daily, because of the cost to replace the part plus labor I decided to keep track of the mileage instead of having it replaced. Now I'm having a whole other issue I am only able to pump $10 of gas at a time because now my fuel pump went out also. When I pump gas my car thinks that it has gas when it doesn't. Now I have no option but the get my car repaired for both issues of which I am doing this week. This is seriously ridiculous. I should not be having these issues with this new of a car. Hopefully something is done about this issue.

The fuel gauge on our 2006 chevy Trailblazer has failed along with the check engine light coming on resulting from numerous codes. The entire fuel pump/filter/sending unit has to be replaced (a $300 part) and the vehicle won't pass and inspection without it. Gm needs to recall this vehicle for this problem and refund owners who have spent money fixing the problem if they want to continue to stay in business.

Spring of 2010, I encountered an erratic malfuncting fuel gas. I actually ran out of gas just once! gauge would show full, empty, fuel light on, gauge moving up and down. Some days it worked fine. I finally had the "fuel pump assy / sender unit" replaced at a cost of $762. That fixed the problem. Not happy!.

Fuel pump issues on a 2006 Trailblazer.

The fuel gauge sensor is malfunctioning in my 2006 chevy Trailblazer. In reading on-line posts, this is a common problem that gm is ignoring. I already had to pay out of pocket for a rear differential that snapped about 7 months ago. Now I have to deal with a gas gauge that could potentially leave me out of gas or even cause problems with the fuel pump.

Fuel pump registers empty all the time, intermittent check engine light (especially just after refueling). Auto will not pass emission inspection due to check engine light. Started just after warranty ran out. Bought the car with 16000 miles on it in 2006. Have recently run out of gas very suddenly, causing a dangerous situation in a high traffic intersection. Gauging gas by mileage is very inaccurate due to heat fluctuation, air conditioning use, etc. No recall? 1000's of complaints on the internet.

I just bought my used 2006 chevy Trailblazer a few months ago, and almost immediately began having problems with my fuel gauge. Everytime I would fill up, the gauge would malfunction and read empty. The low fuel light would come on and the chime would alert for low fuel. Eventually, after driving several miles, the gauge would begin working correctly. However, the problem has gotten increasingly worse over the past few months. Sometimes the gauge would not correct itself at all, and often the check engine light would also come on. More recently the fuel gauge rarely corrects itself and I have to constantly keep track of my mileage and "guess" when I need a fill up. Upon researching this problem online, I've discovered that there are an alarmingly large number of gm owners who have experienced this same problem! supposedly, the repair requires a new fuel pump, sensor, etc. Of course, since the tank has to be dropped, this means a high labor rate as well. Most people report a cost of approx $800 to correct this problem! luckily, my vehicle is still under manufacturer warranty, but with the outrageous number of owners with this issue, gm should be required to step up and take responsibility! a recall definitely seems to be in order!.

Erratic fuel level readings on fuel gate. Once this started it was regular and would read full, empty, partially full regardless of actual fuel level. Replaced fuel pump module and level sensor. Old part is not still available. I am reporting this because I heard there is an investigation I had a 2006 Chevrolet Trailblazer extended 2wd we had no safety issues as we discovered it was not working and monitored miles driven to prevent running out of fuel.

Fuel gauge does not read gas got fuel pump replaced and now it does not work again. 2006 chevy Trailblazer LS v6.
