Elec woes, crank, no start after running then parked.

You cannot really rely on resistance readings with pickups, here is why

There seems to be a lot of manufacturing differences, which means that resistance varies.

If it measures quite low, say, less than 50 ohms, or open, infinity, it has to be bad.

But let's say you check the reading and it seems to be in range. It might have a partially shorted winding, due to moisture, insulation degradation, or vibration, etc. In other words it is possible to measure resistance what you might think is OK and yet not put out enough trigger signal.

Best to substitute, and best to have "some kind" of a second distributor, even if worn and greasy.
