The power steering pump may not be working properly and not producing any pressure. The pump would need to be checked for proper pressures using a tester gauge set. If the pump is producing enough pressure then the steering gear box control valve is bad and not allowing pressure to assist the steering. The pump is the most likely cause of your problem but the pressure control valve on the pump could also be the culprit.
