2002 Chevrolet Blazer: wrong fuel gauge reading

Filed Nov 24, 2014 · Fuel system · 90,000 miles · IL

The fuel gauge sensor system becomes faulty after 74,000 miles. Mine started at approx. 90,000 miles. I have learned online this has happened to many 2002 blazer owners & gm will not address the issue. Because of this the cars will not pass emissions due to a diagnostic trouble code & costs over $1,000 to repair on a 12 year old vehicle even thought it has nothing to do with the actual emission output. It is one thing to have parts break down with age and quite another to have the same part become faulty on a large scale. I cannot renew my plates due to the emission failure and cannot afford to fix a gage for a $1,000. Gm needs to recall the vehicles and admit their fault using a cheap faulty part to save $$. I know this may not be a "safety" concern per say but gm advised me to make a complaint with the federal safety agency. My vehicle is my lively hood & I don't know what else to do.

Fuel gauge jumps from full to empty all the time regardless how much fuel is in the tank - making the gauge useless for displaying the amount of gas in the tank (same thing happens on my 2001 blazer).

Tl*the contact owns a 2002 chevrolet blazer. While driving approximately 5 MPH the contact noticed the fuel gauge reading fluctuating. The contact was unable to determine the accurate fuel amount that 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 75,000.

Fluctuating fuel gauge and erroneous readings on quantity. Repaired 6 times since 01/03. Since repair to PCM, gauge now only bounces in park and neutral but locks on wherever needle is when put in gear to show that amount of fuel. Also reads different levels upon start of engine.

Not long after I purchased my 2002 blazer, I started noticing that at random times the motor would start racing when I started the engine. It ran very loud for a period of time and then would finally slow down. While driving the vehicle this would also happen. The rpms rapidly increase when accelerating, and it would make a loud roaring noise, but the vehicle doesn't go any faster. I took it in to the shop and was told this was normal, that it was the clutch fan. It is extremely hard to believe that this is normal for a new vehicle. I have had the blazer since april of 2002 and it continues to do this and has sometimes put me in very unsafe positions. This problem seems to me to be more of a transmission problem than a fan. I have also had problems with the fuel gauge. It will show empty when it has plenty of gas. It has showed low on fuel, and then when I stop to get fuel, it will not take any gas. But then I have run out of gas right after trying to put some in the tank. The third problem is the left front door hinge. The pin continuously works out of position and it feels like the door is about to fall off and it doesn't close properly and I have to have the pin knocked back into position. Also, at the time I purchased the vehicle, it had a cassette player and the dealership agreed to install a cd player as part of the purchase agreement. The vehicle also had optional controls on the steering wheel. When they installed the cd player, the controls on the steering wheel no longer worked. When I asked them about this, they just said that this cd player could not be controlled from the steering wheel contols and left it at that. I think they should have installed one that could have functioned the same as the factory installed equipment.
