If no water comes out the taps, then it could be a blocked line, or pump is toast.
Also keep an eye on the bilge
while water pump is running. If there is a burst hose somewhere, all that water is going to the bilge
You mentioned a leak, so that means water is flowing to that point at least. You could open that connection( power to the pump turned off) and cover with a bottle or rag(to prevent spraying everywhere) and have someone flip the breaker on briefly.(1-2 seconds) that will tell you if the pump is working or not(in a rough and messy fashion) If you have extra new hose, you could put a length on at that point and out a hatch
or into a sink(much cleaner way)
If there is good flow, then the hose going to the sink is plugged or the tap mixer is blocked. If no flow, then the pump isnt pulling water and it's either a block on the intake, or pump is toast.
