You would want to verify the oil pressure at an idle, and revving it up, with a mechanical gauge plugged into the oil sending unit port. If there is low oil pressure, that is generated by the lower end main and rod bearings. May have worn crankshaft bearings.

how many miles? try running a thicker oil, if that works then you deff know you need a oil pump. if you have high miles then you pretty much need a oil pump. do not drive until it is fixed or you will ruin, if you didnt already the motor.
