What's missing? Spark or fuel? Sometimes the basics lead the way,
Merry Christmas,

I'm not too worried about the spark color. Try some starting fluid in the intake for any reaction which would lead to a fuel or fuel pressure problem if that works at all, T

Possible but just a couple teeth on timing chains will still react if not run.
Compression test would tell you and I bet you should see about 125 or more if things are close or correct. They last quite a while but poor maintenance or real high miles can change that. A history of hard overheating if so will also play a role, T

Like I said -- if it jumped a couple teeth it would still react to starter fluid by bucking, backfire or something. Somewhere around 3 or 4 teeth off you won't get much of anything.
If this is the case the engines sound a bit funny even cranking. The compression drops way off so it has no resistance so cranks too easily.
Vehicles with timing belts have more problems with total breakage than ones with chains. If this totally broke you wouldn't be getting a blinking spark at all. Cars with crank sensors probably would still give you blinking spark -- hasn't happened to me so not sure on that point.
Remember we may be off to the wrong diagnosis here but it would be nice to rule this out, T
