Hopefully someone will know how to fix this, but I have a 95 Yukon 4wd 4dr and at first the fuel gauge was sporadic. It bounced everywhere with no control. So I replaced my fuel pump. The old fuel assembly level arm seemed disconnected and wobbly so I assumed that was the problem. Put in the new pump and nothing changed. Checked ground at pump. It was dirty so I ground down to the bare metal to make sure it was a good connection but that didn't do a thing. Then replaced the gauge clusters entirely. Now it's stuck at 3 o'clock. You can move it to empty then when you start it, it runs right back over to 3. Idk what to do now. Any suggestions would be great considering I'm roughly 300$ in on trying to fix this one problem.

Hey "Zsisk4" Here's some info for you.
FUEL LEVEL SENSOR
The fuel level sensor consists of a float, a wire float arm, and a ceramic resistor cord. The position of the float arm indicates the fuel level. The fuel level sensor contains a variable resistor, which changes resistance in correspondence to the amount of fuel in the fuel tank. The powertrain control module (PCM) sends the fuel level information via the class 2 circuit to the instrument panel (I/P) cluster. This information is used for the I/P fuel gage and the low fuel warning indicator, if applicable. The PCM also monitors the fuel level input for various diagnostics.
FUEL GAGE
The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gage defaults to empty if:
Reviewing the fuel system description will further explain how the system functions. Refer to:

- The PCM detects a malfunction in the fuel level sensor circuit.
- The IPC detects a loss of class 2 communications with the PCM.
