Nistune NA2T not turning over on it's own

Hi everyone, I managed to get my Z31 rebuild to turn over for the first time today, but on starting fluid. I can't get it to turn over without it, and was thinking it has something to do with Nistune. I don't know a whole lot about Nistune yet, but I changed the injector size with no luck. Any advice is appreciated!!
