It could if one of the sensors is not picking up or sending the pulses correctly.

Are you sure Q37 is installed?

Yes, the resistor is there. I've looked 100% and it's ran before. Cars been sitting for awhile so just wondering if maybe the distributor is no good.

If I was to check voltage while cranking...what should I be reading at each pin out?

You cant check voltage as it is a pulse. You would need an oscilloscope to properly measure it.
