Power steering issue

[69bigblock]

Here's the problem. After a long winter a gremlin got into my car. Here's my set-up.. Unisteer power R&P/unisteer type-2 pump w/remote reservoir/mustang hydroboost. Last fall I finally put everything together and it worked fine. I put about 5 miles on the car before I parked it and everything was good to go. Started the car up today for a few minutes and heard a noise steering was very hard to turn. Pump and pressure line was hot. I took the line off at the HB from the pump and fluid was coming outof the pump. Took the line off at The HB going to the R&P and fluid was coming out at the HB.. Took the return line coming off the at HB and no fluid coming out of he line that would return to the HB. Took the line off the cooler which is the line coming out the R&P and no fluid coming out.. There's fluid ging into the R&P but no fluid coming out. Thats my problem..
Now does that mean my R&P is shot or something else?

I talk to unisteer today and said to take out the check valve. So I took the rack out and took off the line going into the rack and there's something there but not sure if its the check valve. I didn't want to start sticking things and prying things apart and making things worse if its not it.. Just not sure if its the check valve or not.. There's fluid going into the rack but not out..
