Bleeding the Power steering pump on a 201 16V

[MDE3]

I recently just had a complete rebuild of the timing chain assembly, which involved removing the timing chain cover. To do so involved removing the power steering pump, which had no previous issues. The reassembled car now has very limited if any power steering. We have rotated the steering wheel lock to lock in an attempt to bleed any air from the system, more than a few times....That seems to have helped a little, but only a very little...any trade secrets I need to know?

Car is a W201 16V auto.

Well we fixed the pump....apparently while sitting around for 10 days while off the car, the ancient oil (it was pretty viscous when we (Royal We..I didn't do a thing) pulled the pump)....must have set up like glue and locked the vanes in the retracted position...amazingly they stayed there even though I took the engine to redline a few times...must have been really stuck...an hour soaking in a solvent and they could be pried free..cleaned the pump barrel and the vanes, re-assembled, and it now works like new.
