Yesterday I checked all electrical circuits to the furnace, all good. In fact, when I turn the thermostat on to furnace and crank the temp, I hear the valve click, but no blower noise and no sound of flame or ignition. After a few seconds the valve clicks off, end of story. Still a mystery, I was planning to search the forum for similar issues later tonight.

You probably do NOT hear a valve click as the gas valve will not open until the circuit gets confirmation the fan is running via the sail switch. You may be hearing the relay click to supply power to the fan but if it's not running you may have a failed circuit board (likely; common problem) or a failed fan, or a bad connection.
