     There is a thread on checking the gauges in the tech section by bd I believe.  You can start there, then I would check the sending units to make sure both are good and possibly that they are indeed hooked up and the wiring is good ( not shorted or cut, etc. etc ).

Considering everything is hooked up properly and you have electric sending units; You can just take a wire and ground out your sending units..
If they top out; then your sending unit is bad..
Otherwise it's your gauge.
