Sound like a stuck/bad sending unit.
Next test is to remove the sending unit from the gas tank. Connect the wire back into the sending unit stud. With a jumper wire connect one end to the base of the sending unit and the other to a good ground. Next you should be able to slowly move the float up and down while watching the gauge. The gauge should follow the float movement.
While moving the float slowly it should move freely. If there is any sticking along the way, the sending unit is bad. If the gauge do not follow the float movement, sending unit is bad.
