Problems with 2000 Chevrolet Blazer FUEL SYSTEM, GASOLINE

Ever since i own this vehicle, the ignition switch does not lock. therefore it is possible to leave the truck and not know the ignition switch is still in the on position. also, the gas gauge bounces all over the place and i have to use the trip to know when i need gas. this has also been a problem since i own the truck. occasionally, the low fuel light comes on (i know i have fuel) and the truck starts acting like it's low on gas. *tr

Always smell fuel while driving replaced all fuel systems then all sensors needed replacing so i did that and now there telling me i have a electric problems since buying this vehicle new i put over 6000.00 dollars into and i still have all the same problems mostly with the fuel system i still smell alot of fuel when driving and back firing and shutting off in the middle of driving i have all my receipts from work done on the whole fuel system and i've looked up this kind of blazer and everyone who owned one has the same problems. *tr

Tl- the contact owns a 2000 chevrolet blazer. while driving approximately 65 mph the contact noticed the fuel gauge reading fluctuating. the contact stated he was unable to know what the actual amount of fuel was in the vehicle. the vehicle was not taken to the dealer for diagnostics. the vehicle was not repaired. the vin was not available. the approximate failure mileage was 70,000. ds

Gas gauge does not work jumps around. *tr

The gas gauge fluctuates. do not know the proper amount of gas is in the tank. *tr

The fuel gauge does not work. it goes from empty to full all the time no matter how much gas you have. *tr

Fuel gauge fluctuates wildly between full and empty when tank is less than half full. if you look it up the gmc jimmy which uses the same fuel system has the same customer complaints. you never know how much gas you have in the tank. this caused me to run out of gas on a interstate highway in the middle of rush hour and i was unable to pull over to the side because of traffic. luckily no one ran into me, but it did create a bad traffic problem. gm refuses to admit this a problem but the mechanics i've talked to say this is a problem they have to repair all the time. this vehicle should be recalled before someone gets injured or killed. *tr

I have a 2000 blazer and i have been having problems with the fuel gauge for the last 6 months. it fluctuates between full & empty constantly. once it hits a half tank, it stops keeping track of how much gas is in the tank. haven't had it fixed yet. seen too many complaints now, gm should replace for free. *tr

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! *tr

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. *jb

Front end is junk,the smell of raw gas when fueling up and replaced oil line, steering parts, door pin, back light, right hub, before service warranty was up. then of coarse the, rotors went along with the left hub and heater core went,.. the blazer has been a lemon since i bought it new. cried alot.. i just turned the 100,000 on 7/15/10 couldn't go anywhere cause it was in the shop being fixed... lemon so much for buying new. *tr

Fuel gauge fluctuates violently and rapidly regardless of the amount of gas in tank. problem has existed for over two years and appears to be a common defect with part. attempt to replace however options are limited due to sending unit and fuel together as one unit. *tr

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. *nm

I own a 2000 chevrolet blazer, 4 dr. lt model. the fuel gauge is erratic and will bounce all over the range, whenever the fuel level is at approx. 1/2 tank or less. this has caused me to run out of fuel, on the highway, because i thought that there was fuel in the vehicle; but the gauge was not registering correctly. the local dealer wants over $900.00 to fix this problem. in doing some online research, this appears to be a very common problem, and gm should issue a recall and fix this problem. *nm

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. *jb

The handle that allows you to recline the seat broke off flushed with the seat, this happened to both the driver and passenger seats in june 2005. the hood will not pop up when the lever was pulled until one banged on the grill or the hood in certain spots, which just started in march of 2007. the gas mileage dropped from 20 mpg to 16 mpg within 6 months. the back glass stuck and was hard to open, started in 2006. when turning on the air conditioner (a/c ) the car had no power, i have to turn it off when accelerating on the interstate or on hills. if the cruise control was set it kicked off when the a/c was on. when i needed to stop quickly the brakes failed, and felt a grinding sensation through the pedal, but the mechanic changed the brakes and checked the rotors, but hasn't found any problem. suspected a defect somewhere in the brake system\ as of 2005. the fan kicked on all the time, even when the engine was cold, and in winter when first starting. one mechanic told me that in many blazers the catalytic converter broke off in the muffler, which had to be replaced. had been told this happened so much that most people left them off. too many other problems to mentioned. also, the horn worked only when it wanted to, problem in the steering wheel. *ak

2000 blazer ran out of gas on the highway. the fuel gauge was on full. this was at 9pm at night. *tr

I have multiple complaints, the gas gauge on my vehicle stop working and i ran out of gas in the middle of the street when i realized problem 2 the rear brake lights and hazard lights do not work. the other problem is the vehicle stalls, and when it finally take off, the car jerks and the driver seat moves/slides back from the hinges which caused me to not be able to reach my breaks and run into a curb. also the driver side door sticks and is difficult to open. lastly the wheel baring and ball joints have gone bad twice and the car has less then 75000 miles on it. i called gm customer service department and explained all of my concerns and was told they we not aware of any nationwide problem and there was nothing they could do except fix the hazard light malfunction. i researched on the net and found many many people complaining of the same concerns i have. *jb

I was driving to texas over christmas and after i stopped in colorado and got fuel by the time i reached wichita kansas is when the fuel gauge started to stay at full when i knew it was almost empty. the gauge bounces around when it is in park or neutral. i travel a lot and it makes it very difficult to judge just how far i can drive before i have to refuel. no repairs have been made as of yet. *nm

We purchased a brand new 2000 chevrolet lt blazer and now the fuel sender will not work properly. therefore, we do not know how much gas we have in the tank. per my brother's inquires on a website he found out that there have been numerous other people that have had this problem and was told by a gm technician that this was a defect in this make/model, they are aware of the problem. i think it should be a recall and the consumer should not have to pay to have this repaired since they know it is a defect and is costly to repair especially since the vehicle is not very old! *nm

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. *ak

The fuel gauge needle didn't register the amount of gas in the tank. it would move back and forth erratically, dropping down to e with a "fuel low" warning and then immediately going back up to f. my mechanic had to put in a new fuel sender and pump at a cost of $670.00. *nm

Fuel injectors on chevrolet blazers ~ original problem was the modulator which i had replaced then 6 fuel injector had to be replaced. i was told by numerous dealerships that the injectors are faulty but to date no "recall". any assistance you can provide would be greatly appreciated.*ak

Sending unit/fuel pump broke so my gas gauge doesn't work properly. gas gauge works from full to half a tank of fuel. from half to empty the gauge doesn't move. i just want to see if others are having the same problems. running out of gas could be dangerous. *jb

Fuel gauge swings between ? and full and sticks at half. both front left & right side hub bearing assembly failed right side not as bad as left had both sides replaced-these are critical parts as they hold wheel on axle-i am second owner of car bought from dealer - dealer took 20% off total bill-defect not dealers fault but chevrolet?s-called customer assistance told nothing they can or will do for me am still trying to get full refund for parts&labor for defective parts that should have not failed at this low milage.

2000 blazer started surging. after several months of surging, one day car would not accelerate on highway and a few minutes later it stalled. it restarted but after several blocks, it stalled again. this kept happening. car was towed by aaa 67 miles to my dealer. dealer could not find anything wrong but thinks it is probably the fuel pump. car is still surging. after 1.5 months car stalled again while idling in a line of cars. it restarted after some difficulty. i then took it to another chevrolet dealer. again they couldn't find a problem. said they couldn't do anything until something showed up on the computer or car completely dies and won't restart. so i don't feel safe driving the car since i don't know when it might shut down on me in a dangerous situation. *la

The fuel pump,line and tank are faulty at 35000 miles. i bought it as a used car from santa ana hyundai who agreed to fix the fuel pump but did not. the transmission is not changing gears properly, it would not start when i turned it off to get gas on 9-26-03, the left front end is popping with a loud noise,the brakes are not antilock brakes,it feels as if i am hitting metal when i stop hard,the panel lights would flicker, lights on dash board when flash when i had seatbelt on. i had a chevrolet dealership fix the minor things. the battery cable was loose and they oiled the joints to stop the squeak. the dealer refused to fix the fuel pump which is unsafe and demand i pay him money that is already above the price of this car. i am paying $14,000 plus for a 2000 chevrolet blazer with a faulty fuel pump.the door entry will not properly take in the key to open the door.the gauge meters were dancing back and forth and not properly reading the fuel.it was a rental car before i bought it so i had no real history of recalls or mechanical reports. *la

Car died while driving, condition occurred 5 times usually when engine cool. technician said they found fuel pump to be shorted out and replaced it.*ak

Service engine soon light stays on and idles rough sometimes won't start. fuel guage swings back and forth not registering the gas level.goes from empty to full.

1. secundairy airpump 2. multifunction switch (initial recall never rec'd, only reimbursed for $218)

The right rear and both front brake flex lines failed on two separate occasions. the consumer reported the problem to the chevrolet headquarters and was told there was no recall or warranty for the failure. *mr *cb *nlm

Severe water damage and mold. bogging down in engine when at complete stop the truck will not accelerate.*ak

The fuel pump needed to be replaced on my 2000 chevy blazer because the sending unit was corroded, also the handle on the side of the drivers seat broke off when i used it. *jb

My 2000 chevrolet blazers fuel level sending unit went out after 6 mos of owning the vehicle i bought it used in 2003 and all the sudden the gas gage wasn't working so i took it in to see what was wrong and i was told that the fuel level sending unit went out. so i started asking around and a lot of owners of the same make, model, and year also complained that theirs went out as well i got quotes on how much to fix it and was told that the price range was $380-$460. and i would have to replace the whole fuel tank just to get it fixed. also the rear-end differential broke and it took 3 months to finally find one because the manufacturer doesn't make the part for that year anymore. i am very disappointed in the quality of my car and strongly regret buying it with all the problems it has. *nm

Acceleration pedal hard to push, acts like it sticks. the dealership cleaned the throttle body, they said that there was carbon build up which caused the sticking. this is the second time i had this cleaned. when i asked the dealer, he said this was very common with the 4.3 v6 engines. dealer recommended adding fuel injector cleaner to stop the build up of carbon. i had been doing that. seems like it lessened the build up but did not prevent it. i suppose this is going to be normal maintenance, similar to an oil change. i have had other blazers and have never had this problem, it would be nice if the manufacturer could resolve the problem. ts

Numerous electrical problems and or failures, bad fuel and exhaust problems, suspension pops excessively, gas pedal sticks intermittently, radio replaced twice, electric seats and windows malfunction

I purchased my 2000 blazer in 6/20/02 from a chevy dealer in pa . i purchased the extended warranty . i have until 6/07 or100000 miles i have replaced the coil and distributor cap and rotor 5 times a new fuel pump a catalytic converter windshield washer motor and turn signal switch it has gotten to the point that i can't even sell it to anyone private and i can't afford to keep it . there has been electrical and computer issues shorts that melted the fuse box under the hood that melted the relay for the fuel pump. 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 had the motor mounts replaced twice in 4 years. i have never been notified of any recalls orservice notices . i have had the vehicle serviced by licensed mechanics and had it serviced at the appropriate mileage required for the warranty. *nm

Acceleration pedal hard to push acts like it sticks. throttle body was carbonated up. dealership cleaned throttle body and sticking stopped. the sticking usually occurred at start up but it also happened if you removed your foot from the gas pedal during driving to slow down and then reapplied your foot to accelerate. i put up with this for about two months before i had it serviced. ts

While driving the fuel gauge fails to indicate the correct amount of fuel in vehicle, at times the needle would indicate a full tank when it was empty or vice versa. *ts *nlm

Throttle almost always sticks when vehicle movement starts causing learching starts. dt

While driving on the highway at 50 mph a red light flashed, indicating something with battery. vehicle suddenly stalled, and power steering went out. vehicle stalled 7 times that same day. consumer felt there could have been a rear end collision.*ak dealer replaced faulty ignition switch, fuel pump, and module. *slc
