Try replacing the regulator if you get no gas flow, or very weak gas flow. If you have gas flow and you are trying to light the grill with the ignitor. The rotary piezo ignitions must click with each turn, if they don't then they are bad and need to be replaced. If you have a new lynx with the glow plugs, check to see if they are glowing, if they are glowing and the grill has gas and still won't light, then the glow plugs are not getting hot enough which means you are leaking current somewhere and have to trace everything down to find the short.
