Andrew, have a read of how the key, the EWS and the DME/DDE work together - it will become obvious how you can get a crank but no start when the EWS - DME/DDE sync goes west...
By design, an EWS ident failure (no chip in key, dead key or fake key etc.) will produce a no crank situation but if the EWS is happy with the key, it will allow the starter to spin, even if the DME/DDE doesn't agree with the current rolling code (a sync failure) and stops the ignition/injection etc.
You could say this is poor design but it IS how its designed.
