Was it fine before replacing the leaking pump?

So it sounds like you problem is one of the two things that you replaced, you said you already swapped your old rack back in with no change. So that leaves the pump....

From my quick googling powersteering pressure should be roughly 1000 psi, so sounds like you have a bad pump or pressure relief valve.

The 1000 psi reading is just using the Google machine and putting in powersteering pressure.
