If you touch the sending unit wire to ground, the gauge will go to EMPTY. If it doesn't do that, the problem is somewhere before the sending unit. There's lots of posts on this if you search fuel gauge or something like that. If you take the sending unit out, you can check the resistance of it with a multimeter. They are usually 0-90 OHMs. As you move the float, check to see if the resistance is changing.
