Please advise your level of experience with these cars. It would seem you have not futzed with your car very much yet.
Has the car performance suffered? If so, there is an issue with the turbo itself, ie no boost. I would first check the wastegate rod connector underneath the turbo, jack up the car or go up ramps and look up and you'll see it plain as day - there's a kotter pin that holds that mechanism togther that will rust and break off with age. It is the cheapest and easiest fix to gain 45 HP.
If performance is normal, then its a 'gauge-only' issue.
it may be as simple as the vacuum line that sends the pressure to the boost gauge has become disconnected, or split somewhere along the line (common problem is at the drivers door area where it makes a 90 degree turn. its hard to get at this area so the line could actually still be factory original and thus very old, dry and prone to cracking).
The first place to start is checking under the hood at all the vacuum lines running hither and yon, mainly from the intake manifold outwards to various components like the bypass valve, charcoal canister, vacuum advance etc. if they are all fine, then follow the line that goes towards the drivers door and then dives down a hole and pull on that line. if it comes up, broken, then that's your problem. to fix it you'll have to (probably take out the air distribution vent and the sound insulsation foam in the footwell in order to reach and see up in to the area, and run a new line (or use a male to male connector to go around the break.
the other possibility is that the line has become disconnected behind the turbo gauge itself. if you pull the drivers speaker , you can shine a bright flashlight down into the area and perhaps see the line or the connection where the line should be.
So that should give you a good start. report back when you can.
