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?

None I can think of...

As gasoline moves from your gas tank to your engine, it passes through the fuel filter (FF). There are small particles in the gas that can clog your fuel injection system and wreak havoc within your engine. The filter prevents this from happening. This component allows gasoline to pass through while small particles and debris are caught.
