Blowing injection fuse

My daughter has a 94 Protege that burnt a wire that controlled the stereo and fans. Found the wire and replaced it. Hit the key and nothing. It attempted to turn over but would start. Next thing I know it blew the injector fuse. I replaced the fuse three times and even replaced the fuse box still the car wont start and worse it continues to blow that one 30amp fuse even when the key is in the off position. Any ideas what would cause this?

I'm having trouble posting. I'll try this approach. When the wire burnt, it probably burnt the wire to the injectors. The insulation was most likely damaged but the wire wasn't grounding out. When you replaced the burnt wire you probably shifted the injector wire so that it's now grounding.

Fans are ECU controlled. And shorting or grounding in that circuit could have easily done damage to computer, which could easily be blowing injector fuses. Check powers and ground to ECU. A good test is does the check engine light do a self test when you turn the key to run? Also when a scanner is hooked to it, does the computer communicate? If not, ECU may be blown.
