Your leak could come from any part in the system ,if your serp belt is oil soaked ,the most common cause is the output shaft seal behind the pulley on the pump. Another common leak located underneath the vehicle could be the return line which runs from the pump to the front frame rail the to the rack (very common for leaking) Also either pressure line or rack could be leaking .
Because you have a leak.

Rack and pinion power steering.
Check and make sure the rack is not also leaking. I ended up replacing the entire system (everything that had power steering fluid run through it) in my 94. Also the power steering pump turned my fan - you run out of P/S fluid and your transmission burns up.
