Were the pump vanes installed correctly?
Reverse installing them can cause a no pressure situation. Was the pressure relief valve checked? If the valve is stuck open, pressure would not build up. It is best to have the pump pressure tested before going on as the symptoms indicates a pump fault. As to the reservoir, drain it and check the strainer/mesh inside. If it is dirty or clogged, you would have to replace it.
