Hopefully the good thing is it's most likely a bad switch since there is no power at the pump. Two tings I can think of.
First make sure all switches are all the way up or down and none stuck in the middle.
Second is you said all fuses are good but did not say if that was a visual or a meter check. If you are not aware the fuses have two windows located at the end of each blade where you can check that current if flowing through without unplugging the fuse. Set your meter on Volts DC and at the fuse panel poke the positive lead into the window and the negative lead into a ground point. Check both windows on each fuse. You should get the same voltage on each.
