How are you measuring the voltage? Coils get their power from a single feed that jumps from coil to coil. MPU supplies the individual grounds to each coil to fire them. Are you measuring the voltage by putting one lead of your meter on the banded side of the diode and the other to a known ground? If so, and you have no voltage here but you do on others, then the wire from coil to coil has broken somewhere. Trace it back to the previous coil.
