I do not have a manual for your car so I cannot give you specific terminal information..... I do have a manual for a 89 Riviera and suspect the system is very similar. It shows a 4 position connector at the pump, one wire is hot all the time (happens to be orange/black in the Riv) One wire goes to ground and that is almost always black One wire goes to the level control sensor (this opens and closes the air line) The last wire comes from a RELAY (which could be bad) the relay is turned on by the level control sensor. and the 12v line going to the relay is only hot when the key is on. If either of the fuses are blown the system will not work If the relay is bad, the pump motor will not turn on.
