Gas Gauge Malfunction

Nokesville, VA

#61 Nov 8, 2011
I have a 2002 Chevy 1500 truck with 168,000 miles and the gas gauge has started to do crazy things with the low on fuel light coming on all the time. Even with a full tank the problem continues. I have been told that this problem is caused by the float in the gas tank having come loose from its mounting in the tank. It appears to have not been bolted in place but GM used some form of adhesive to hold it in place and this has lost its ability to keep the unit in place so it can work properly. The tank has to be dropped, the fuel pump removed and the float system reattached to the gas tank. Chevy should have a recall on this poorly engineered system that is causing this type of problem. We did not have this problem with older vehicles when the unit was bolted in place within the tank.

I have a 2007 Trailblazer with only 44000 miles and the gas gage goes to empty while running. What's that about American made?

I jus bought a 2001 chevy blazer and I've noticed that the fuel guage always messes with me as I had to slam on brakes for the first time, and the car made a loud noise, and I assume that it was just downshifting...but I've never driven a car that made that kind of noise before when I slam on brakes..afterward when I pushed the gas petal it felt a little stiff, and as if I broke something lol.. I dont know what to do about the gas guage, I've heard that if it says that it's empty it's possible for the car to act as if you dont have any gas in it and not start up for u.. this might be common for some of you guys, but this is one creepy car for me.. rear hatch doesnt work..or I dont know how to open it..
hi, no, I think you know how to open the hatch, it's just messed up, just like my 2002 blazer, the power locks don't work, and the gas gadge doesn't work right when it gets below a half tank. Seems to be common in the trucks. I'm trying to figure out how to fix te problem my self, with out having to take it in to a shop.

My 99 s10 trucks gas guage jumps from full to empty all the time. Its annnoying cuz I have to play a guessing game and she sits on 43s.. I can get about 120 miles on a tank on long trips if traffic is good and in town depends on traffic and how hard I drive her.. My brothers 01 silverado does the same thing.. It should be free for chevy to fix their fuck up. Funny thing is my 89 s10 blazers only problem is sometimes when I use my turn signal the wipers will go one time..

Is anyone who knows about this just glad to see people spending money on stuff they don't need. GM has a replacement harness and wiper arm for the fuel level resistance grid (the wiper arm is the real culprit). I don't know the part number.

I have a 2004 4x4 Blazer and today I went to fill-up my gas tank and I could not pump any more than 1-2 liters, less than 1/2 gallon of fuel when it started overflowing. I am told that the fuel ventilation system is probably clogged up. Has anyone ever had this problem and if so could you help me out on how to go about fixing it. Any help from anyone out there would be greatly appreciated. Thank you in advance.

Try turning the key ahead but don't turn engine over wait for the security light to stop flashing ( may be 10 min ),turn key off count to 8 try starting.

My parents bought me a 2000 blazer. The fuel gauge is messed up, it will stay on full until about halfway thru the tank, then it will drop to e, gas light will come on then after a few seconds then it'll. Jump back to full. When I'm really on e the meter willdrop back to e and the gas light will go on for about 30 miles, til the engine stops. And the service engine soon light has been there since they bought it, sometimes it'll just be there, other times it'll flash.

Rides very well tho. I hope nothings wrong with it
