I have verified continuity of the wiring to the #8 ignition coil, so I suspect the DME. Do you have any ideas what might be causing the non-firing on #8 cylinder?

my guess would be the ecu as well as long as everything else has been ruled out.
are you getting any fault codes? misfire on #8 etc?
sometimes a vacuum leak can cause some carnage.
