S300 Installed Now Won't Start

[T03KNEE]

So it turned out somehow when I loaded a base tune I didn't do it properly or the fuel maps weren't accurate for what my car needed as the local tuner near me made me a base tune after hearing it almost start with the stock ecu and it would've fired up the same if the battery weren't so dead. I'm gonna go swap the battery right now and then see how she idles because it was a tad bit rough but he needed the info from my wideband to fine tune it better, so I think the culprit was just a bad tune preventing the spark plugs from firing?
