 Does your furnace have a Honeywell "smart Valve" system? You can tell by the valve having two "molex" plugs on it. I can't tell you how many bad "smart Valves" I've seen cause the problems you describe.

The only other thing I can suggest is make sure the furnace is grounded properly and make sure your pigtail has that center ground prong in place.
