Why does my gas tank gauge not move?

What to do if your gas gauge reads lower than it should?

When the gauge reads lower than it should, check at the gauge by disconnecting the wiring from the tank unit. Turn the ignition on and if the needle reads full or above, the gauge unit is probably good and the tank unit or the wiring leading to it are probably the problem. Reconnect the tank unit wire to the gauge before proceeding.

What causes the gas gauge needle to move?

The variations in the amount of fuel in the tank cause the arm to move. This changes the resistance of the tank unit, changing the amount of current at the gauge unit coils, which in turn moves the needle located between the coils.

Why is the intake gasket on my Vortec cracking?

On the 5.3L vortec, the intake manifold is made out of plastic, and the gasket was poorly designed. Due to its plastic material, the manifold itself is prone to cracking either from it being overtorqued, or simply from natural wear and tear as it operates in a high-heat environment.

What happens when your gas gauge is not working?

What to do if your fuel gauge is not working?

With doing the fuel sending unit, your replacing the pump and the thingie that reads the fuel level so you kill 2 birds with 1 stone as the fuel pumps don’t generally last very long in the GMT-800s. Just a FYI, try to avoid driving with a tank below 1/4 as the fuel also serves as a way of cooling the fuel pump/sending unit.

Why does my gas gauge read full or above?

If the gauge reads full or above with the wire disconnected, the problem is in the tank unit rather than the wiring. It could be an electrical fault, or the float may be stuck or may have sunk because of a hole caused by corrosion. Remove the tank sending unit and check it.
