Remove the sender wire going to the gage.
It’s the same purple wire referenced below* you will use if you decide to add a new gage.
Tape the removed sender wire so it can’t short.
Connect a 47Ω resistor to the gage where you removed the sender wire.
Connect the other end of the resistor to ground.
Turn the key to RUN.
If the gage is good it will read about ½ way.
So, if the gage is good, you know the problem is the sender or the wiring going to it.
*Behind the dash on the left side of the car there is a connector.
Cut the purple wire (but leave enuff to resplice in case you cut the wrong one) and connect that wire to your new gage.

Sending Information
The sender wire (purple wire) travels from the connector located behind the left rear seat to the back of the dash.
Wherever you tap into it or reroute it is up to you.
Electrically it makes no difference.
