Shooting from the hip here... But I have a '90 9kt so couldn't be too far off.
1. Check fuses in glove box, the ECU for the apc system is under the driver's seat, rare, but maybe a bad connection (Big plug like the other ECU's
2. The 3way switch on the back of the radiator (Top right as you look into the engine bay) It controls when and if the turbo works. There are some tests described on this BB elsewhere , but I can't remember where to search and for sure you'll get feedback on your post besides mine.
3. Look for split hoses on the pressure side. I think you'd hear this problem if it existed but it's worth a check.
Are you sure it's not working or just not making the boost guage go up?
A break in the vaccume line will let it (pressure) escape before it can register on the guage and it will affect performance.
