2000 Chevrolet Blazer: fuel pump failure

Filed Jun 13, 2014 · Fuel system · 98,000 miles · CA

Gas gage bounces around and fuel light comes on even when I know the car has a full tank. I have to track mileage every time I put gas in the car. I also have a problem with fuel pump not getting power and r I have replaced the fuel pump 3 times and it will have the same problem days to wks after replacing the fuel pump. I have searched on google and their are many people having this same issue. I have taken it to 3 different shops and no one can figure it out I am very frustrated. Their is code that shows up when tested. The car has broke down many times with my daughter in it. I never know if I turn the car off if it will start back up. At times in the morning it wont start at all and my daughter is late to school due to the car not starting and having to find her a ride. For the past 4 days the car will not start at all. Their is no power getting to the fuel pump. I am so frustrated!!

At 90,000 miles my fuel gage became erratic, chevy dealer says it's the fuel pump. At a cost of $800.00 to fix I'll calculate my mileage and live with out it. Gm taking low bid on the fuel pump means I no longer buy gm products. Fix mine at no cost and you got me back.............maybe!

I bought a 2000 blazer in 2002. I took my vehicle overseas in 2003. Much to my surprise, the gas gauge stopped working properly one day in 2004 causing me to run out of gas on a major international interstate. I took it to the dealership when I came back to the states only to be told, that something was wrong with the fuel pump. Not only that, the module also has to be replaced because the fuel pump and module comes as a unit and you cannot replace the fuel pump without replacing the module. I am being told I have to pay $950 to have this problem fixed. I know I am not the only one with a blazer who is having this problem. Gm has failed time and time again to acknowledge this as a manufacturer problem and people are losing money because of it. If I have to pay $950 out of my pocket to fix this problem, this will be one unhappy, loyal customer gm has lost because I will make sure that no one I know ever purchases a gm vehicle again.

I bought the 2000 blazer used just over a year ago and have had nothing but problems. To begin, I replaced the alternator, fuel pump, and virtually all suspension components in the front end with just over 65,000 miles. On vacation during one of the hottest days of the year traveling home the blazer over heated and left my family and I stranded on a major interstate with no A/C for nearly an hour before getting towed to the worst chevrolet dealer in the country(richmond, va). We were forced to pay for a new radiator and miscellaneous parts totaling over $600. They said the coolant system was full of rust and the radiator was plugged and could not be reused. Now I'm experiencing the service engine soon that will not go out. After numerous trips to the dealer that started with leaking oil cooler lines, they said that the crank sensor was going bad. I replaced it, still the light stays on. Next they say there is a misfire in cylinder 2, I replace the plugs, wires, rotor, and cap. Still the light stays on. All of these repairs within the first 14 months of owning this junk and it is not anywhere near being paid for. Gm needs to fix these problems. I have spoke with other blazer owners and they too have experienced nothing but trouble. And the big 3 wonder why they are losing customers and market share. Have they ever heard of quality? Looks like I'm going foreign.

Also there was a short that wiped the computer codes out and I had a rough time passing emission testing I am at the point the extended warranty does not want to spend any more on the vehicle.

I have purchased a 2000 chervolet blazer, I have a faulty fuel pump gauge, one that will never tell you the right amount of gas. This lead me into running out of gas at a very uncivilized area, and it could have ended up being a wreck, if a emergency lane wasn't available. A few weeks later I learned that a entire fuel pump was needed to correct the problem. I researched this on the internet and from talked to other people with blazers: they all have the same issues, gas problems, and I believe chevy is in fault here for producing a faulty fuel pump to thousands of owners. This part costs $400 to replace.

Ball joints upper and lower replaced at 40k and 100k miles. Will be needing to be replaced again very soon at 140k miles. The replacement at 40k was a total failure of passenger side ball joints to wit: vehicle was incapacitated as wheel was left 'bent'. Fuel gauge fluctuated wildly if less than 1/3 tank of gas. Fuel pump failed.

I have had numerous problems with my 2000 chevy blazer ls 4x4. Under warranty the dealer replaced the oil lines by the oil filter, whole seat mechanism, driver side window motor, rear shock. They also fixed my hood rattle after 5 visits to the dealer and I told them what was wrong the first time it went in. Since then at 40,000 miles the driver side wheel bearing went out and had it replaced and at the same time had the fuel pump replaced since that went out also. At 50,000 miles the same one went out again and had it replaced. Now at 68,000 miles the passenger side wheel bearing is bad. Also on my first wheel bearing replacement, they told me the ball joints were very loose and should think about replacing those also. These things should never be going wrong with such low miles. From what I am reading on the web and hearing from the dealers, this is a very frequent problem that chevy will not recall and take responsibility. I sure am happy that I haven't had a wheel fall off and kill someone yet.

Numerous problems. All after warranty expired. Have a 2000 chevrolet s10 blazer 2 dr. It is a 4x4 with a 4.3l v6. Seat handles broke a couple of times. Terrible lifespan on those. Had replaced twice.*ak replaced defective alternator. Wasn't holding charge. Also LED to a new battery and serpentine belt. Had to replace fuses for fuel gauge. It was jumping all over the place giving incorrect readings. Had to replace numerous fuses. Terrible whining coming from the fuel pump. Chevy dealer tells me it is testing fine. But now I am having what seems like vapor lock problems on hot days. I'll go to accelerate and the vehicle will go no where and then catch and accelerate. Acts like it's going to die but hasn't yet. Diagnostics showed nothing. Terribly sporatic and makes vehicle unsafe and unreliable. It has 60,000 miles on it now. Ongoing problem to this day and I'm trying to determine if the lack of acceleration is the pump or another problem. Pedal not sticking like it was a throttle linkage. Rear windshield pump does not work. Chevy rim caps keep breaking and coming off. $30 dollars apprx. For each one and have had to replace all four at least once.

2000 chevy blazer 4.3l v6 76k miles 2 door the sending unit on the fuel pump has gone bad and is causing my gas gauge to give an incorrect reading. I must now use the trip odometer to guess when to put gas in my truck. From research I've done this a very common problem with blazers of this year. Gm should offer a recall for this $600+ job also replaced the upper & lower ball joints, idler arm and both wheel bearings in the past month. Seat recline lever on passenger side has also snapped off and rear washer fluid sprayer no long works. I've owned 4 other chevy/gmc vehicles and had to replace the fuel pump in 3 of them. I will very much consider these issues and how gm handles this most recent one when I go to buy a new truck next year.

The fuel sending unit is operating erratically, causing the gas gauge to be inaccurate. The cost of repair is $400.00 for a new sending unit/fuel pump and $200 for labor! I have heard from other gm owners that this is becoming a common problem. Gm will never get my money for a new car again if they don't own up to this problem.

On five separate occasions the vehicle stalled while driving at any speed. The driver was able to restart the vehicle. The vehicle was taken to the dealer and they were unable to duplicate the problem. *jb the engine shut down without any warning at any speed and while idling in park, the engine restarted. The problem could not be duplicated. The gas filter, ignition wiring, and the fuel pump was replaced but the vehicle was still experiencing the same problem. *sc
