I doubt the ECU was affected; it just knows what signal it receives, not that any signal irregularity would affect what it's programmed to do. Mine was fine (still throws the knock sensor code above 4k but that's a different issue I'm still trying to run down without replacing the ECU to eliminate) after the sub-harness replacement. You are correct, I didn't pull anything on the engine, just threaded it through. I would check every injector sub harness connection, looking for bent pins, etc on the male sides and debris inside the female side to see if perhaps something went awry when you replaced the connectors first, starting w/ #2 and the main plug going back to the rest of the harness after verifying they're all connected to the correct cylinders.
Not sure with the fuel ref the injector and how susceptible they are to fouling; maybe run some cleaner (Seafoam, etc) through a small amt of fuel first to see if you can get it to clear all of them out after sitting so long. I just went through gummed up carb orifices on my son's Kawi after letting it sit too long w/ ethanol fuel in it, but haven't ever worried about my ST (I put stabilizer in it and left it sit for a year in FL, started it up and ran out the tank as soon as possible before refilling it with fresh and never had a problem.)
I'm sure others will weigh in if there are any errors in what I've mentioned above; ppl are pretty good at catching the details for us here! Just try to be as deliberate as possible on the troubleshooting so you can eliminate things for sure and provide info for others to offer further assistance based on what you find.
Confirm you had a long and three short blinks?
