oil pump issue? on 1997 Pontiac Grand Prix GTP

hi i have a 97 grand prix gtp that seems to have a ticking sound like a lifter is tapping and the low oil life light flashes when its running. It just recently developed this problem and i was wondering if it could be the oil pump because the car shows full on the dip stick.

Yes it could be. Remove oil pressure sender and attach gauge and check pressure at idle and higher rpm's, compare to spec.
