the car will crank but will not start. There is no ignition (spark) to the plugs. I have changed both crankcase and camshaft position sensors, but the problem remains.
Looking in the oil fill hole, I can see the camshaft turn so the timing chain is not broken but could be stretched.
I assume with a stretched timing chain I would still get spark, but out of sync. Am I correct?.
What else would cause no ignition?

Hi,

Yes, you should still get a spark. However, does it sound different when cranking? Is it possible for you to record it cranking so I can hear it?

Now, if you lost spark from all coils, one thing that they have in common is a grounding location. Take a look at pic 1. Check to make sure the connector isn't damaged, loose, or corroded. I've seen them get weak enough to show continuity, but fail when a load is placed on them.

Start with that and let me know what you find

Take care,
Joe
