If the LED glows dimly and then goes out, you may have
1) weak battery (not enough voltage and it can't spark
2) in need of adjustment/cleaning of the burning chamber. Again, if
you don't have a strong enough battery for the sparker to bridge the
gap this can be adjusted by cleaning the tip and moving it slightly
closer to the burner.

Based on your symptoms, I'd check the voltage at your battery first.
