Have you ever had the timing 1 tooth advanced and experienced it for yourself? I simply ask because it is a learning experience.

If the base timing is 1 tooth off, or if that sensor is faulty to allow the timing to be too far advanced during cranking, it does give the dead spot symptom. The starter can crank the issue over at normal speed, and the starter and engine will come to a total dead stop. It may resume before you release the key to re-try it.

I've experienced the issue first hand. The TSB also mentions this to a degree.

This issue fooled so many people.

A quick test could be to disable the ignition system, and crank over the engine and see if it turns over normally several times. This is what I had done to isolate my issue.

I'm not saying that you are wrong. I could be wrong. I'm trying to help.
