First let me say there is no easy way to pull the pump. It will be a knuckle buster. Now with that you will remove the drive belt then you will move any of the following needed out of the way. The tensioner and the strut housing tie bar. Disconnect the power steering lines. Remove the bolts holding the power steering pump on. You may have holes in the power steering pump pulley to gain access to the bolts. Then remove the pump. Now you will need to rent or borrow a power steering pump puller and put back in reverse order. Let me know how it goes.
