Other than ohming out the wiring harness going to the guage, and then ohming out the connector on the float assembly, and looking for a change when you move the float up and down, then id say the sending unit is bad. I don't know what the float is supposed to ohm out at, but you should be seeing a big change in reading

I was afraid the unit was bad lol got a salvage yard near by guess ill see if they have one i can try hopefully it fixes it

I unplugged the sending unit and it still reads full as well

Bump found the yellow/white wire split in 2 put it back together but still stuck on full....

well messing with it again today i got the gauge to work when moving the float around but as soon as its put back in the tank it goes back to reading full again...

also i just unplugged the terminals to see if maybe it will reset itself
