I hope they have told you all of the ways to ignite the flame/burners. The saftys are the first step and is one thing you can allways count on. It will allways be the same with fuel systems. If you have no ignition then look to what you do have and most times you will see it. Use your meter to isolate problems. It can be easy at times and other times you need to really look. Thats what makes it fun for me and allot of other guys.
