Well as you have replaced the pump (and can now hear it turning) the last thing it can be is a blockage in the bottle or an earlier pipe as I suggested. As I say, get the wheel plastics off again, unplug the tube (that takes the washer fluid up, through the 1 way valve and through the jets) from the motor itself and operate the wash then. if you STILL get nothing, there's something jammed in the bottle I would think, or you have no screen wash
