What should the voltage be on the fuel pump?
Remove the fuel pump module so you can manipulate the float arm. At this point, with the key in the ON position (but without starting the engine), back-probe the connector and check for voltage. You should always have 5 V or 12 V on one of the pins.
What are the parts of a gas gauge?
The gas gauge system can be broken down into three basic parts: gauge, sender, and circuit. A fault in one or more of these parts will lead to gas gauge failure. The sending unit is usually part of the Fuel Pump Module : a combination of parts that includes the fuel pump, fuel strainer, fuel filter, and fuel float.
What happens when your gas gauge is not working?
The gas gauge tells you how much fuel is in your gas tank and alerts you when it’s time to refuel. If your gas gauge is not working, the inaccurate information it provides may cause you to run out of gas unexpectedly.
How is the gas gauge in the instrument cluster?
The gas gauge in the instrument cluster is the visual indication of activity in the fuel tank and sending unit.
