Engine running, when working the steering wheel, can you see fluid circulating in the pump?

With engine off, you can take return line loose, aim into container, rotate the pump pulley with your hand, see if fluid comes out. The return line isn't as heavy duty as the pressure line, you should be able to tell by looking at the lines.
