Did it make any noise or just dead silence?
Mine has some issues either with the impeller plus it had something wrapped around it that prevent the motor from spinning (hair maybe). Unless you listened carefully you couldn't really hear it try to pump.
As far as a fuse, mine is wired direct to the panel. Its a circuit breaker on the panel. Some older panels have fuses instead. Do you know what panel you have or do you have a photo of it?
Catalina installed mine with just standard butt connectors (not the heat shrink waterproof kind) at the pump. They weren't corrosion resistant but they do allow you to check them with a multimeter. You could try testing it before you do anything to see if it is getting power.
Also, if the pump is clogged there is a screw on the back of the pump that you can turn to try and free the pump. It didn't work on mine, so I just replaced it. I don't rebuild macerators.
