i think that you're mistaken

if either one is gapped incorrectly or broken, the engine will not start.

if the phase sensor has a fault during driving, nothing happens on L8, but on lesser ecu's it will cause a misfire

if the crank position sensor fails, the engine will not run.

as far as i know, that is the situation. i look forward to being corrected, as that would mean that i would learn something
