Could have melted a wire, or burnt out a relay. When the fuse blew, it was because something was already overheating from too much amperage. When you bypassed the blown fuse, you stopped that little bit of safety, so whatever it was protecting, it was no longer protecting. Find out what that fuse went to, and start by tracing all of its components
Quite likely either the killswitch shorted out or the starter solenoid has taken a dump. you can cross the posts of the solenoid with a screw driver with the ignition in the on position. if it starts then you have a bad starter solenoid.

replace the fuel pump relay, it is burned closed from the shorted fuel pump.
SOURCE: fuel pump fuse blowing
replace the fuel pump, it is drawing to much current, this is common when the pump bearings get worn out, also make sure you replace the fuel pump connector at the fuel tank connection, it will be burnt..

I have been working on a simular problem on my daughter's vehicle. with the following additional symptoms. It only fails while hot. Runing fuel preassure checks, I noticed that the preassure rises from 30 psi while running to 40 psi after turning off the hot engine. This is caused by the expansion of the fuel in the rail. I believe that this hgh preassure is causing the regulator to stick closed preventing the fuel to get to the rail during a restart, (as the preassure drops to 0 while the fuel pump does whirrrr during the startup proceedure). It seems to free up after it has cooled then works normally. We ordered a new regulator but haven't received it yet to see if this fixes the problem. There is a possibility that the problem is a weak pump that cannot overcome the stuck regulator but since all the checks are in spec, I'm leaning toward the regulator at the moment.
