could be your actual ecu. I'm pretty sure if it's a fuse all the injectors would be going crazy so i don't think it's that. Could be your wiring too bad ground maybe(long shot)? If all else fails it's prolly your ecu but don't quote me on that.

Eliminate the wiring for that cylinder(injector): Depin at the ecu for the trigger ground, run a wire from the ecu to the problem injector. Do a KOEO verification, If that injector still has an issue it's the ecu!

Key On Engine Off

If you do pass that test, I wouldn't see any harm in firing it up!
