power steering wont bleed please help.

[carnahkt]

Hey I put a new power steering pump on my buddys 91 7mgte and it worked great at first then after about 10 minutes of running it started to whine so I figured it was a defective pump. I put a new pump on along with a new resovoir because someone had taken the screen out. So I got it all back together and this time it wont bleed out manuely.When I turn the wheel back and forth (engine off) it starts to overflow fluid, like its sucking air in somewhere. I took it back off and checked the suction line going from the pump to the resevoir and everything looks perfect. I also took the idle control valve out and looked at it because someone disabled it, so I pluged it on the outside in case air was getting sucked in there. I put it all back together and everything went fine, and it worked great like the first time but then it started whining again. so I shut it off immediatly and checked the fluid and it was all foamy, so I tried to bleed it out again and again it wont bleed it, it just overflows. I am baffled by this. I have checked everything. There are no leaks and everything on the suction side of the pump looks fine, the screen is clean and the line is not collapsing. I am putting atf in it.
Could this have anything to do with the idle control valve being disabled. I put the pump w the hydraulic reaction on it because it does have the wires going to the rack so could that have anything to do with it?
Please help me. This makes no sense to me, Ive tried everything with no luck.
