Are there any problems with the fuel gauge?
Since you have +12V to the gauges, that means that one of four problems exist for the fuel gauge and the temperature guages. (They will have to be diagnosed seperately since the problem with the fuel gauge circuit might not be the same as the problem with the temp gauge circuit.)
Why does my gas gauge keep pegging full?
The gas gauge might interpret voltage feedback from a dead sender as FULL or EMPTY, consequently pegging the gauge no matter the actual fuel level. Circuit Problems can cause the gas gauge to stop functioning normally.
How does a fuel pump work on a gas gauge?
The fuel pump module includes the fuel sending unit, used by the gas gauge to detect and display fuel level. https://www.flickr.com/photos/3ndymion/33556245572. The gas gauge is a relatively simple circuit, but its simplicity means each component is essential to its function.
What does + 12V mean on oil pressure gauge?
Since the oil pressure gauge is working, then you have the +12V into the cluster on these pink wires AND any possible “refernce ground” source for the gauges is probably there as well. Since you have +12V to the gauges, that means that one of four problems exist for the fuel gauge and the temperature guages.

How do I change the temp on the fuel gauge?
Disconnect the wire from the sending unit and run a length of wire from that connector to a nice clean ground on the engine. The sending unit wire should be dark green by the way. Once again, sit in the driver’s seat and turn the key to the on position. The temp guage should immediately jump to HOT side of the gauge.
Why does my gas Guage reading read full?
I know from experience that disconnecting the wire at the sending unit in the gas tank will cause the fuel guage to read full. There is also a ground wire on the fuel guage sending unit which tends to get rusty and break off after a few years. If this happens, you will see the same problem – fuel guage reading full.
Where is the temperature guage on a car?
The temperature guage is a little easier to test. The temp sending unit is located on the intake manifold on the top left front right near the thermostat housing. Disconnect the wire from the sending unit and run a length of wire from that connector to a nice clean ground on the engine.
