Yup, spins with no sign of firing at all!  It only spins easily by hand when
the plugs are out..  otherwise it is a one-compression-at-a-time kind of
exercise.  Compression is normal..  I am well familiar with its feel.  I am currently leaning toward a intermittent condition with my CAS wiring or
the bad gas/flooding issue.  At least it has made me think harder about my
CAS as a single point failure and review the wiring.

Thanks for all the suggestions.

nothing changed from my flight yesterday except for adding fuel.  But it
won't start...   I verify that I have fuel pressure, fuel flow, injector
function (in test mode), I have spark (in test mode).  Maybe it is
flooded... I change the plugs, re-verify spark in cranking mode (to
eliminate issues with CAS), re-drain the fuel, verify compression, re-verify
fuel pressure and flow and injector funcion... but still it just turns over
without starting...  Sigh

Anyone one know of a new component necessary other than fuel, spark, and
compression?
