No power steering assistance on MX73 1JZ

Just been doing some more testing on my MX73 1JZ swap, and found another little problem...
At first the power steering was noisy and had gave little power assistance,cleaned out the oil reservoir to find heaps of little pieces of metal so cleaned that out and the noise is gone, but now theres next to no power assistance at all. The pump has been pulled apart and is in good condition, doesnt seem to be any problems there, but just wondering if the pressure relief valve is stuffed?
Tested the pressure and at idle it was only at about 5psi which is about 34.45kpa I think. And at about 2500rpm its about 30psi and then only gets upto 60psi at about 4500rpm. Read in a few books and it says the pressure should be about 800-1000kpa? 
There is so little pressure that I can stick my thumb over the hose and stop whatever pressure is there
