You all beat me to it, bound to be something concerned with the coil boost-volts
feed. I suspect there is no LT feed to the coil whilst cranking but the engine
makes it over another compression sometimes owing to momentum when the key is
let go and this cylinder now fires.

Good thought Gordon, Also..... on Ford the resistor switching is done with the
starter relay so
check that also.
