suspect the pump as the other post ended up being. if you have bled the system and there is no air in the system (little bubbles or a frothy looking fluid) then it would seem like the pump isn't working or possibly has a stuck open relief valve. lots of times the new or rebuilt pump has vanes that stick in their slots so the pump doesn't move fluid like it should. check to ensure the lines are connected properly as well. (to the correct ports on the box).
