Those gas solenoid valves are problematic. I had to replace a couple on a dryer, and my downstairs furnace currently has a bad one I just have not dealt with. You can see if the solenoid is getting energized with your meter (just hook it up across the wires-- check them too for continuity -- either at the solenoid or the controller), if it gets juice and doesn't open then you need a new valve (or maybe just the solenoid). They are not very expensive if I recall.
WARNING: Working on these can cause dire results, up to and including death, dismemberment, dyspepsia, distention, disorders, dystopic tendencies, strabismus, sterility, and other conditions. See your doctor. Ask not what you can do for your country. Vote for change! Change your underwear. Hope to count your spare change.
