Gas Gauge Doesn't Work?

You'll have to check to see if the sender is getting any power or not. Here is the diagram check either the dark blue or light blue wire by the tank to see if it blinks. If you hit the right wire the gauge should go to full if you probe it. If it does then it's your sender which may have to be bought as a unit, meaning the pump/sender assy. Check out the images (Below). Please let us know what happens.
