The question was to rule out the possibility that fuel was not getting into the motor. If you cranked the motor for some time, there should have been plenty of fuel in the cylinder, hence a wet plug. Also, if you cranked it for awhile, pulled the plug and cranked the engine again, you should have had a mist out of the plug hole.
Your troubleshooting for an electrical problem seems to be spot on.
