No Spark help

I understand how you feel lol. My entire season last year was fd due to electrical issue(s).
Mattax advice with drawing out YOUR schematics(if you have made mods/changes) is a good idea. Took me about 6 tries to get it, pretty sure its accurate now. Helps solidify in your mind how its wired and works.
It could be a coincidence/timing with your problem.
Take a couple days off. Make sure to keep notes.
Good luck.
