break light electrical

Thanks guys, I will check the ground at the brake light soon. but I think I already manually grounded it the other day and it still didn't work.

Yeah, I tested the voltage at the coil during cranking and the voltage went up, but still no start. I have fuel/air, what else would it be? Started and ran the day before but the next day it just cranked and no fire? Is there something I'm missing??????

Thanks
