Power Steering not working

Hey guys, have a 73 dodge dart sport with a 360 and headers in it. I put a reman ps pump in it and two things i can't figure out.

first, it is leaking but it is not leaking from any of the fittings. there is oil on the bottom of the pump and it is dripping on the cross member and floor. Where's my leak??? :angry1:

Second, the ps is not working??? :help: Loosened the in line on the box and fluid came out, took off the return on the box and fluid came out. help please!
