The pump will let water flow though, that's normal. Unplug and plug the harness back in the pump sometimes the connection gets dirty. If you can't get it to run it's the pump. The pump is just press fit into the tank, it will pop out and you can put in the new one. It's pretty simple, the tank is held in with 2 - 10mm bolts then it just lifts right out after you unplug the pump harnesses and hoses.
