BMW E36 M3 First Start in 10 YEARS!!! & No Spark Diagnosis

After what feels like years of research and tearing apart an already torn apart car I finally get it started. I start the video by looking if changing the crank position sensor made a difference at all by checking for a spark in multiple ways. After confirming that it made no difference I dive into the ECU by trying to repair the factory one, after failing to fix it I install a new ECU that I got off of eBay.
