Power steering

[GunnerSchenck]

I'll just try and keep it simple..
After replacing the power steering lines and fluid, I lost power steering.

Could I have cause something to go bad by incorrectly purging the air out of the fluid? Such as the rack or pump?
Could the power steering switch be the cause? I didn't replace it, just put it into the duralast line prior to installation.
Any help?

Ended up being the pump if anyone ends up coming across either of my threads during a problem search.. new oump..bleeding it properly and new fluid after a flush..good to go.. thanks all
