Weil McLain Won’t Ignite

I have a 10ish year ole Weil McLain boiler - model 1107-1 that is giving me issues with igniting. The startup process seems to go well and a spark is initiated, but the boiler fails to light. I’ve included a photo of the unit. The top “flame” light on the control board flashes when attempting to ignite. I have cleaned the boiler and checked/cleaned the igniter rod, but that’s as far as I’ve gotten. Any addition insight would be appreciated!

Theres obviously 24v to the pilot valve. Is there 24v to the main valve?
Gas pressure? Lockup and manifold.0 -
Clean the pilot tube/assembly.0

Practically speaking: spark + gas = ignition.
If you see the spark and know it's there, check the gas.Contact John "JohnNY" Cataneo, NYC Master Plumber, Lic 1784

Is that the pilot only burning in the photo ? If so did you try cleaning the flame sensor as well as the igniter rod. Also check your ground wire make sure it,s tight.0
