I put it up on jacks yesterday to see if a line had popped off to cause the massive leak. However I did not see anything detached. How could I determine if the pump has failed?

If at all possible, don't run it out of PS fluid, because the pump won't take that for very long.
If you're a DIY type person, all I can think to do is get a friend, get the car into the air, top off the reservoir, and keep it topped off, until you can determine where the leak is coming from, repair the leak, and then see how the pump behaves.
Or, put it on a flatbed and have it towed to a professional.
