Power Steering Problem

I was driving and my power steering just *click* ...gone. No assist. Okay I check the belt, still good. I check the fluid, still okay. I replace my power steering pump, okay that's done but no assist. I replace my rack and pinion, okay that's done but no assist. I'm lost fellas, I don't know if i did something wrong or maybe another part needs to be replaced or what... Can anyone offer ideas?

 

Similar issue?? Hope you get it figured out...Good Luck

When you replaced the pump, did you get a new reservoir, or did you re-use the old one?

 

Jammer,
I read through all of that and it looks similar however I already went through one pump I'm on the second. The second pump still whines and I drove it while still not having any power assist. Could that have caused this pump to go bad as well? I just replaced the rack today and I had a heck of a time doing it as the new bushing made it difficult to mount. I turned the wheel stop to stop about 3 times but It still may have air in the system, it looks like smooth atf no bubbles though. I wonder if maybe I messed up on the install or if its just air in the system or even that its a bad rack and/or pump. Augh! serenity now...

Yes I already ripped it out, intending on cleaning it and reinstalling it. However, that proved to be easy to clean but difficult to reinstall. In the end I just left it out.
