I believe that you've misunderstood me. Can you NOW light your stove top? If so then you've eliminated the things that I think are the most likely culprit. It doesn't matter how you fire it, the question is does it work?
If you CAN still fire the stove top then you've eliminated these easy things: no propane in the tanks, the tanks are turned off and/or not properly switched on thru the auto switching device.
