My experience is with a 2002 Impala so this may not apply, however since I had an identical problem and it is a GM product also, here goes: The fuel level sending unit had corroded, bent, contacts. My unit was inside the gas tank and requires quite a bit of work to remove. A very helpful website for this is www.impalahq.com

Connect a freon tank and gauge to the Buick Century low side ac port. Start the car and turn the ac to high. Open the tank and allow freon to flow. Shut the tank off when the gauge reads full.
broken fuel gauage sensor or possibly a broken fuel pump indicator
fuel gauge quit working on 1997 buick park ave. what is it?
The fuel gauge in a 1958 Buick Roadmaster typically operates with a resistance range of about 0 to 30 ohms when the tank is empty to full. This resistance is part of the variable resistor (or potentiometer) in the sending unit, which translates the fuel level into an electrical signal for the gauge. However, it's always a good idea to consult the specific service manual or documentation for precise specifications.
I need to know how to change the temperature gauge from Celsius to Fahrenheit on a 2012 Buick LaCrosse
If the gas gauge on your 2002 Buick Century is fluctuating, it could be due to a faulty fuel sending unit, a problem with the gauge itself, or an electrical issue. Start by checking the connections at the fuel tank and the gauge for any loose or corroded wires. If the connections are fine, consider replacing the fuel sending unit or the gauge. If you're unsure, consulting a professional mechanic for a thorough diagnosis is recommended.
Connect a freon gauge and freon tank to the low side ac port. With the engine running and ac on high, open the freon tank to fill the system to the full line on the gauge.
A Buick with a 3.8 liter engine does not have an oil pressure switch. There is an oil pressure gauge. The gauge can be accessed by removing the dashboard panel. Unhook the wiring harness to the gauge. Reverse the process to replace the gauge.
have an experience mechanic test you fuel pump fuel level sensor, which is part of the fuel pump, ground the wires and if the gauge pecks gauge is good. if it don't you have to replace your cluster which is a seal item and must be replaced as a unit. do not try this yourself.
