Bob,
The only thing I could think of would be to pressurize and depressurize the gauge with air over and over for a few minutes to see if that will finally loosen the gauge up enough to make it useful again. I'm assuming this is a Bourden (sp?) tube pressure gauge with a little lever acting on the needle. Perhaps some water found it's way into the gauge and you have a little corrosion. Of course, if the tube leaks that's a gauge killer.
A risky alternative would be to remove the glass face cover of the gauge and directly lubricate the the action and free up the needle.
I like to save stuff and the savings are not my motivator but sometimes a new gauge is the way to go.
