Well, since no one came to the rescue yet, I can give you a hint to get you started. Replace the blown fuse with a pair of crimp-type spade terminals, then use a pair of small jumper wires to connect them to a 12 volt light bulb. A brake light bulb should work fine. When the circuit is powered up and the short is present, the bulb will be full brightness. It will get hot so don't set it on carpeting or against a plastic door panel.
Now you can start unplugging things and shifting wire harnesses around to see what makes the short go away. When it does, the bulb will get dim or go out.
Unplug the Engine Computer, mass air flow sensor, ignition coil, ... Things like that. Sorry I don't know what else is on that circuit. You might look at the wire going to the fuel pump, and the harness going to the oxygen sensor. They usually have a 12 volt heater inside that turns on with the ignition coil and injectors.
