Power steering issue

[Raceaprilia]

Power steering was working fine. I had minor leak out of power steering pump at the seal body to housing. Pulled it out, resealed and put back together. Did the bleeding procedure on jackstands repeat it several times but no luck. I have no power assistance out of the pump. When I pull return and place it on top to return in fill hole pump is pumping fluid just fine trough whole system. Where did I go wrong? when I put it together for the first time while building truck all went together without any issue and worked since day one. Am I missing something?

Thanks for any input.
