I have never had tank level indicators that were accurate, Usually after a good cleaning they will work better. I used to put really hot water in mine with a cup of simple green and drive around a few minutes then drain.

Not to be a Smart A$$ but is the propane valve turned on? On my older C I had to bleed the air out after it would sit a while. If water heater and furnace won't light off I would suspect that is the issue. Bleed out at the stove.
