The fuel guage always reads full. Have changed the sending unit in fuel tank and re-soldered a joint on back of fuel gauge that was cracked but gauge still reads full always, does not fluctuate at all.

It goes off the sending unit signal to the computer reading. Go iinto onboard computer to bcm inputs and get to fuel level what does it read. That will be your fuel level. Push off and warmer on a/c panel to get in than go to bcm than bcm inputs find fuel level read it. Use the high button for yes and the low button for no. If it stays on full you may have a open wire from the tank
