Answer
Dennie,

The pressure switch mearly bumps the idle speed up to compensate for the extra drag on the engine.  If the new pump does not provide pressure there will be no power steering.  I would run the steering lock to lock and make sure the air bleeds out of the system.  If this does not work the new pump is not working.  The pressure switch will not cause you not to have power steering.
