Sounds like there is either some sort of obstruction or the pump is shot. I'd try to figure out if the pump is actually circulating fluid through the steering system hoses. (look at my two other ideas below first) I think if you pull one of the cooling lines off the front cooling loop and have someone carefully and slowly turn the steering wheel to see if any fluid comes out. If I'm not mistaken, the line that is just clamped to the bottom of the reservoir is the return line from the cooling loop. You can remove it from there, but wherever you make the disconnection, you will need to some how plug it or clamp shut an open hose or whatever to not loose the fluid out of the reservoir. You also don't want to completely drain out the reservoir to not hurt the pump.
There may be a check valve on the high pressure side of the pump that's a metal line at the pump to the rack that may be stuck and not letting fluid through, or you have a bunch of sludge in the bottom of the reservoir plugging things up. Some have a screen at the bottom that has plugged up. If that's the case, you may as well do a full fluid flush and exchange, which an explaination for can be found with the search function at the top of the Taurus page.
Hopefully, anything I've described that's off, someone else will set straight. Let us know your progress and solution!
