You could start with ignition key on and check for 12 v at the Vacuum Pump. If no 12 volts...then fuse or wiring....if 12 volts...then vacuum pump.
If vacuum pump....pressure sensing circuit or pump circuit.

Is that the same location of the Vacuum Pump Fuse for the 1990?
Thanks for the information......

However, it turns on every 2 seconds or so when key is on. Vacuum leak?
