If you were off by so much as a tooth when you put the gears in time you never will sync.

Then you may have a rare PCM failure. PCM's rarely fail it is useually the FICM's that have a high faliure rate. Also may be wireing between FICM and PCM.

So you do sometimes show a good cam/crank sync? Do you always have a clean scope signal? If it comes and goes try cleaning the mounting surface for the sensors, just a little dirt or rust can give a bad or no signal. I've heard of loose tone rings but have never seen one myself.
