'95 GSR doesn't HAVE an A.I.R. pump.
That's the ABS pumping up. Check the fluid reservoir over at the ABS unit. Maybe you have to bleed air out of it? Maybe it's more serious than that. Read the ABS trouble code & post back. If you find a list of codes posted, beware - '98+ cars have a different system with a different set of codes.
