I did not try to light the tank with n o water in it. I do not use the water pump. I always hook up to shore water. One less thing to winterize. I always have the hot water faucet open. Otherwise there is no other way to know when the tank has filled.
I have pulled off each terminal connection and checked them for corrosion. I will try to replace the ignitor and see if that helps.
I tend to think its the module based on the fact that at one point, when turning on the gas switch inside the rig, I would hear the gas valve open, I would hear the ignitor clicking away.
Like I had mentioned at one point, I was able to manually light the flame using a long reach ignitor.
Thanks for the input.
