[T3] B brain

[Mark Reno]

I hear the relays click and I can feel the relay under the dash and the one
behind the seat click. It won’t start. I have checked my timing multiple
times, made sure I have spark, the pump runs, and have checked the grounds.
I am at a loss and it hasn’t run for a few months now. So I’m super bummed
about it.
