4. What does your cap and rotor look like?
5. Did you see if you actually have spark going to that cylinder?
I do plan on buying the proper compression gauge, but I still definitely want someone that knows these motors to have a look at the issue...and yes I do plan on using CAA for this.

All plugs have been pulled, and check out difference with the injector plugged in or not, cap and rotor look new.
