I must admit I have never been overly concerned with coil ohms when I found that different manufactures have different specs and it is also temperature dependent. I have bad coils 1 ohm out of spec and I have seen them bad inside the spec given.
Engine running and was shut off resulting in a no start. Was the engine allowed to set 'X' amount of time before trying a restart or was it immediate? Hot soaking a coil can also result in a no start. That is where the engine is turned off and the heat continues to build as the coolant is no longer circulating removing the heat. Hot soak. If it was an intermediate try to start and no such luck then the ignition key can come into play as well as your ballast resistor which the ignition switch feeds.
Welcome to Ford. They have an official Wiggle Test in which you get to wiggle wires and connections looking for opens and breaks in the wiring. You can also have a wire broken inside the insulation to add to your fun.
Distributor voltage on the ground side of the coil is dependent on the points. If open, you should see equal voltage on both sides of the coil. If the points are closed, the voltage on the ground side should be near zero. This is wher yhou can burn up a set of points when leaving the ignition on without the engine running. if the points are closed, the current will continue to flow and shorten the life of the ignition points.
Engine cranking voltage to the points will be lower as the battery is also being drained cranking the engine. If the starter is dragging, this will lower the voltage going to the coil, then being produced by the coil and ultimately will not produce enough energy to fire the plugs.
If the starter cranks well cold and then slow when warm, you might have a bad starter adding to your problems.

Today's Featured Article - A Lifetime of David Brown - by Samuel Kennedy. I was born in 1950 and reared on my family’s 100 acre farm. It was a fairly typical Northern Ireland farm where the main enterprise was dairying but some pigs, poultry and sheep were also kept. Potatoes were grown for sale and oats were grown to be used for cattle and horse feeding. Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w
