Default Not firing on cyl No. 1

D16 with a fresh ITB install. Consistently not firing on number 1.
It gets fuel (I pointed the ITBs up and they all spray) and it gets spark, but the spark plug comes out soaked. Timing is set at 16.5.
Does that sound like flooding?

good compression on all cylinders, the wire is fine, the plug is fine
i am dubious on those reasons, the car ran perfect before the ITB install.

it is possible it is leaking, but i have seen it open and close during cranking. i will be purchasing a wideband soon, and i will move the injector to a different cylinder to see if the dead hole moves with it

Moved the injector from No. 1 to a different cylinder, dead hole moved with it.
Time for new injectors.

If he moved the injector, and the problem moved with the injector, the problem can only be the injector. 94

I didn't see that. I think I left the browser window overnight. Agreed, it can only be the injector.
