Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your

issue. First I’ll need some more info so I have a more complete picture of you situation.

Do you have 24 volts AC to the gas valve when the igniter is firing? is igniter HSI (hot surface) or electrodes?

It's a spark light a plug

Ok, I need to know if you have 24 vac to the gas valve when it's arcing/sparking to be able to narrow down the likley culprits.

Ok, if you have 24 vac at the valve when the igniter is arcing then you probably have a bad gas valve assuming you have adequate gas supply pressure at the valve inlet.

Ok that's what I was thinking didn't think they went bad often

They don't fail very often but they do occassionally.
