I think you are going to have to dismount the pump first. The pulley is removed by pulling on the snout with a special tool (there are several versions). DO NOT use a 3 jaw gear puller.
Isn't there a hole in the pulley to get a socket through?
This is on a Jeep, but the principle is the same.

Check the Tech Tips section. There may be a tutorial in there.
