I don’t think you have a keyboard or trackpad issue. I’m suspecting the logic board still has issues. Rarely does both fail full out. Lets see if we see more corrosion on the board. If you haven’t already taken the logic board out I would do that following this guide MacBook Pro 15" Retina Display Early 2013 Logic Board Replacement Take some nice tight pics of any area that looks off and post them here for us to see Adding images to an existing question.
