Putting in a higher-rated fuse is a great way to set your wiring (or more) on fire. Diagnose it like you would any other short. From the owner's manual, determine all components energized by the fuse, and disconnect them. Reconnect them one by one until the fuse blows.

My manual calls for a 30 amp fuse for #9, and says it controls the Power Control Module, PCM Power Relay, Electronic Transmission Control, Injector Pressure Regulator, Injector Drive Module. It might be a good idea to check the wiring to the IPR, it might be grounding out, but as Mike pointed out that higher amp fuse might have caused bigger problems.

I'm a little drive away from you and not going to be around for a couple weeks. If you're still having trouble when I get back, I might be able to make a trip out of it... I'm not the most experienced guy with these motors but I'm willing to help!
