My lighting time varies considerably, always has. Same pellets, same performance once burning. Sometimes it seems it’s within seconds after the pot fills, other times it takes several minutes and almost the whole startup cycle. Smoking and sparking the whole time, igniter is fine. I always attributed it to the randomness of how the pellets fall. If one lands right over the igniter hole, they would probably start quick. If they landed to form a large pocket around the igniter hole, it would probably take much longer to ignite.
