Power Steering

I have a 1988 Toyota Supra. The power steering went out on it. I didn't have the time to change out the p/s pump my self, so I bought a p/s pump, and had Pep Boys install it. Only to get it back and the power steering is still not working. They told me it was a bad pump, the place I bought it from says they have never had one bad off the shelf like that. Well, my problem is, if I purchase another, Pep Boys will charge me another $190 to reinstall it. The original pump was bad, it was leaking oil and making noise. The new one does neither. Is there and easy way to check oil flow or line blockage? I don't want to have to install another pump, when this one might be good. The resevoir seems to be backing up and oil is coming out of it. So I have to think that the lines are clogged or something. Any suggestions would be appreciated.

Thanks

Oh........I learned my lesson........don't take it to Pep Boys!!! LOL :iceslolan
