car won't crank fuse box was wet fuse box shorted out

What is your question?

floor was wet by fuse box inside the car passenger side the module that operates the fuel pump number 20 fuse shorted out and the car will not crank the dash lights are on but it will not turn over. on other occasions when this happened I just changed the fuse this time it burnt the fuse holder. It appear that the leak was from the sun roof it has not been draining properly
