The sensor is worn out - it's covered in the gunk that normally accumulates in the tank so the sensor needle sometimes gets stuck or it no longer makes contact. You could clean it but the problem will return quickly.
Just replace the sensor.

What causes gas gauge to register incorrectly on a 2003 Buick rendezvous?


Common issue for Rendezvous is a faulty fuel sending unit, sometimes referred to as a fuel module (fuel pump, pump filter, float, sending unit, all sold together as a preassembled unit). Go to your local auto parts store. Most have a scanner/code reader that they can connect to your vehicle to download any fault codes.

I just replaced the fuel pump in my 2002 buick rendezvous. Now, the car starts, but the fuel gauge doesn't work. When I turn the car on, the needle goes to full and stays there, then low fuel alarm...


Oh my, there is no reset. You would need to remove the pump module and check the gauge sender part, maybe the float arm got jostled or bent when installing.
Sorry to tell you this, it will have to be redone. This time when you pull the unit out of the tank, take a moment to connect the battery, connect the electrical connector to the pump module, turn the key to on, then check that raising and lowering the float arm makes the gauge read right.
It's either this way, or let it be and figure your gas left in tank by number of miles driven.

Gas gauge is moving up to full when i give it gas


Sometimes those gages go bad, or it could be the float on your sending unit is bad, that is in the gas tank, I have an older model truck that can be on empty and I can put like 10 dollars in it and it will show like it has a full tank, and we know with gas prices these days that isn't much gas lol, but more than likely it's sounds like to me that your gauge is faulty.

Sounds like you have a few different problems . GM vehicles had insturment cluster problems from 2003 to 2006 . Something called a stepper motor inside is what drives the gauge needles . Plus the fuel gauge also has a sending unit inside the fuel tank that can go bad . Your idle problem could be the IAC - idle air control valve on the throttle body or clogged air passage . Video's on youtube showing how to check these things .

When I put gas in my tank, I have to pump the peddle to get my 06 Buick Rendezvous to start! It only happens when I put gas in the tank? Any suggestions??


man you only puts fuel when you fuel tank is really empty and that cause the air to enter into the fuel circuit try next time to refill before it gets totally empty and lights up
your car will turn on without pedal trick

Gas gauge problems with 2004 Buick Rendezvous


No, there is not a fuse for this. Unfortunately, you have a bad sending unit. In order to replace the sending unit you have to drop the gas tank. Sooo............drive it more to get rid of all of that gas and it will be easier to put back up.
please remember to rate this solution.
