Question 2010 only running on one cylinder

hey guys,
been a long time lurker on the site, haven't posted much. Ive bought and fixed a few pre-gens with various issues over the years but this is my first newer model 250 and I'm a bit stumped.

I bought it as a non running project and finally have it narrowed down to the left cylinder isn't getting spark.
so far this is what I've checked:

I swapped out the coils and both coils seem to be working on the right cylinder

Fresh plugs are in it, still no spark

One cylinder is firing so I'm thinking its not the crank position sensor

so I'm guessing my issue is lying somewhere within the wiring harness or the cdi is malfunctioning. Any help would be appreciated as to where I should start looking.

Thanks in advance
