That is usually the electrodes not firing because the transformer is
weaker. Try bending the electrode or adjusting them closer together unless
the transformer is dead.
There is a time delay and light sensor in the burner that shuts it off in
30 seconds if there is no fire. It IS possible no fuel in going in there.
If so, trouble shoot fuel.

Before bending them, just try wiping them first. If they are sooted up,
they will not fire.

I once had one that wouldn't fire but would if I gave it a good smack
with the side of my fist. I opened it up to find a tiny string of
carbon looped from one electrode to the other. One good smack would
break the loop and it would start. The cause of the problem was the
last guy to service the burner... ME! I had the electrodes adjusted
wrong. Eventually I learned the right way but have forgotten it by now.
