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.

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?

Details?

Spins with no sign of firing at all?

Spits & pops but no regular combustion events?

Any chance that the extra effort required to spin the engine by hand using the prop through the reduction drive is hiding the fact that you have low compression? The old RX-7  starting trick is fairly quick if you've already got the cowl off. Pull a plug for each rotor & squirt in a little ATF, reinsert the plug & try to crank. Lyn can probably recommend how much. I never measured; I just dumped in as much as I could get in there while fighting all the junk under the hood.
