Hi there. There is a PML valve that is on the rack and pinion steering on your vehicle. Check to see if the valve is working. The PML valve is is the speed sensitive steering valve for the steering system. If the valve gets stuck, then the system will back up in pressure and act as if the power steering pump is not working. If you have already replaced the power steering pump, I recommend replacing the PML valve. If you need further assistance with your steering being hard, then seek out a professional, such as one from Your Mechanic, to help you.
