Cylinder 8 ignition coil isn’t getting any power at all. Coil is new. What do I need to look at to diagnose why it isn’t getting power?

I would swap out the spark plug to start, also once the old plug is out check it over for damage. Here is a guide that can help. The next step is to do a compression test and if that is okay, I would replace the injector, but please go over these guides first then I can give instructions on how to fix it:
