I believe the power will always be there, but the engine control unit (I believe) provides the ground when the pump is supposed to be running.

If the old pump ran but was noisy you would assume the new pump should also run. You could have had a bad bearing on the old one which means it was noisy all the time, not just when it was running, so you should clarify that.

I think it's a bit much saying you were scammed. If you have new pump which was bad maybe whoever sold it will send you a replacement, to say you were scammed at this point is irresponsible.

Well scammed is a little HARCH,but my anger really comes from the fact that removing the old one was very,very difficult and took about 3 Hrs.Removing the long bolt that holds the pump to the housing would not come out. So when i finally got it off and installed the rebuilt on and it did not work,i was very disappointed.BTW: The old pump only made noise when the clutch was engaged.I took the car to Donny [Benzmac] about 4Yrs ago and he just unplugged it.How should i put 12volts to the pump? Can i just attach 2 wires to the battery and stick the other ends to the pump?

Yes, in fact usually even a 9V battery touched to the pins will engage the clutch, no need to run lines to the battery.
