    Potential problem may be in the wiring or sending unit which is in the gas tank with the fuel pump.Any other issues with other guages or lights being on?

Check fuses,remove sender unit from tank,connect ohm meter to it and physically move arm up and down slowly and check for increase/decrease in resistance,if this is ok then supply power to the wiring to gauge and see if the needle rises,if no change in resistance sender is rooted,if no change in gauge when it is supplied power then the gauge is rooted,when diagnosing electrical probs always check fuses firstelectrical

My temp gauge is not working and since that,when the car is hot,it stops everywhere and it is hard to start,like it s flooded ( to much gas )is it the temp gauge the problem!


Hello francis.

If the temperature sensor is defective it will send a cold signal to the computer.
This cold signal will make the engine run rich (too much fuel).
Cold engines need more fuel to run so that is why it is rich when hot.
But...the computer has a separate sensor from the gauge sender.
Which engine is in your Pontiac? 2.2 or 2.4 ?
Let me know here and I will send you some location diagrams.

Hello mcammdf.
To properly test the fuel gauge circuit you will need to check the purple wire at the connector to the fuel tank.
Run a wire from the purple wire at the connector to body ground. If the gauge moves when you ground it the circuit to that point is good.
These cars are noted for fuel gauge problems and most probably the issue will be the sending unit in the fuel tank.
