Heh heh...get the belt back on?

I'm going for the amusing stuff cause I'm (probably mistakenly) assuming you did the rebuild properly and all.

Well, that'd depend on the type of pump you've got. I'd assume the gears are in backwards or something, or there's now an obstruction where the reservoir drains into the pump, or something like that. Could be something as simple as a mismatched gasket set, too.

Also if I remember right, it takes a LOT of bleeding to get all the air out after you change the pump. Lots of shuffling the steering wheel side to side...try unhooking the return line and stuffing it in a 2L bottle to see if you're actually getting flow thru the system I suppose. Make it a clean 2L and you can pour it right back in when you're done. If ya got flow, I suppose you can unhook the feed line off the rack, and turn the pump by hand or with a slow speed drill to see if you've got flow there. If you keep moving up the line and find that you've got no flow coming out of the pump, chances are you've done something wrong with the rebuild.

If you've got flow, I'd guess the next thing you'll be rebuilding is the rack :D though honestly I'd recommend just getting a new one, either out of a junkyard or from a parts shop. That goes for almost any rebuildable part, though. Saves a lot of hassle.

well i kno my rack is fine b/c i didnt have a problem w/ anything before the rebuild i just got the kit for no reason at all pretty much haha guess i got borred but anyways i lifted the front end up disconected the return hose from the resevour and went lock to lock a bunch and holding it at lock for about 3 sec. i could see the fluid come out of the hose on left turns at lock but when i went right it would go back down. but if i did have air in it wouldnt it be growling??

Not always. Generally the pump has to be out of fluid for at least a few hours before it actually starts to growl. On top of that, it'll stay silent even if there's not quite enough fluid to completely cover the gears. Then there's other issues, some pumps just don't make much noise. You'll definitely want to check for flow...just turning the wheel isn't going to tell you anything other than the pistons in the rack are still moving, which is obvious since they're mechanically driven anyway.
