I have no gauge movement at all when the car is started and running and the last I tried touching the sender wire to ground it moved all the way to high
Use a 10 ohm resistor or variable resistor next time for testing any of these gages.
Or do what I did. I had a bunch of 22 ohm resistors. Use one alone the gage should go the middle mark. Use two twisted together in parallel and that's 11 ohms.
Put two in series and that's 44 ohms.
