Keeprite NG furnace code "fail to ignite"

so intial blower kicks in, igniter lights, then that repeats a couple times. Control valve appears to clicks, but that's it? Dont see hear smell gas.
Gonna pull flame sensor and clean.
Thanks

I would not clean the sensor. Some of those combo sensor/ ignitors can get brittle and break easily. I would sure find and buy a spare ignitor
