make sure your system is full of water and can fill, or the new pump wont work either

the pump requires replacement, you could remove the vent screw and use a small flat blade screwdriver to see if it is turning the impellar inside, that may release it if it is stuck, there may be some water and black sludge to deal with so be carefull, definatley your pump is the problem
