hydro boost problems

[marlink1226]

Question, i have a 1986 cucv m1008 with the 6.2. I replaced the power steering pump and ever since have had no power steering or brakes. I'm on my 3rd pump and think maybe its not the pump so i replace the steering box that has a slight leak and still nothing. i bleed the system every time unless im doing something wrong there. the pump i got were from bennet and napa and im not sure the pump there giving me has enough pressure. i it a speacial pump or just a regular gm pump. any help would be great

Just a guess, but I bet you don't have the relief valve in the power steering pump installed correctly. I remember this happened to me (years ago). When I swapped out the pump, the relief valve (that the pressure line comes out of) had a check valve and I screwed up the replacement order (ball then spring or was it spring then ball?) Anyway, no power steering.

Can the Mods move threads that are created in the wrong forum to the proper forum? That might help a bit.
