So I bought 1992 s13 hatch with a rb20det with a bad power steering pump. I bought a new pump and put it on. Replaced a couple of the hoses and checked the hard lines. Currently have no visible leaks. I lifted the car up and turned the wheels all the from left to right for a long time trying to get rid of all the air. I then turned the car on and repeated the steps. At an IDLE the pump sounds fine, but it acts like it doesn't have power steering. If I Rev it up a little, power steering works great. If I go to drive, the pump makes a loud noise like the pump is running dry even tho the steering is great.
Any ideas? This should have been a quick simple fix right?
