Oil pressure problem

Maybe just your gage is faulty, if it was the pump, more than likely bearings would be toast. Put a mech gage on there. Perhaps your vehicle has some sort of kill device if oil psi drops to unsafe level. But its not working if motor is still running. With zero.oil psi.
Im amazed motor is still alive with no oil psi if the pump is junk. Maybe also the pickup screen is severly clogged with gunk to drop psi so low. Or could just be faulty gage
If that's not it not sure.
