Atwood water heater won't light

G6A-8E-SP model number. It was brand new last March. Worked fine last year and this spring. The last outing with it, it wouldn't fire up. What I've covered so far. Turn the switch on inside, the red light on the panel comes on right away but goes off as it goes through it's lighting process. Gas valve clicks and there's gas flow- I can smell it. But no ignitor. After about 5 seconds it clicks again and shirts the gas off. Repeats two more times with the same results. When the gas is on I can light it with a lighter and it fires right up with a good flame but then it shuts the gas off. Tried a new ignitor with no change. Connections are all clean and even ran an additional ground wire from the top of the housing where the factory ground wire hooks up down to the bracket for the ignitor. Still no change. The control box looks like there is two LED lights on it. Are they supposed to light up? What am I missing? Any help would be great. Thanks
