Don't know how you found that, but I'm happy you did. Chrysler had a similar problem in the '90s with their single-cam Neon engines. On those, the Engine Computer will set a diagnostic fault code for "Cam and crank sync" when the timing belt jumps one tooth. It turns on the Check Engine light too. At two teeth off it shuts the engine down to protect the valves. There's your no-start, even though you have good fuel pressure, and often intermittent spark. At three teeth off, the valves can be bent.
There is a dowel pin between the camshaft and its sprocket, and that can shear off and allow the sprocket to rotate over time. That results in late valve timing, just like when the timing belt jumps a tooth, but investigation shows the sprockets' timing marks are right on. I spent days trying to find the first one. Now I learned that was a common problem.
Can I guess that before the crank / no-start occurred, there were other engine running symptoms that might have been a clue this was about to happen?
