Unable to start (no ignition?)

Hello!
My friend has a Zenair CH701 with Rotax 912UL, usage is quite low, average of around 1 hr flight time every 5 months or so.
Recently tried to start up, but able to crank with no startup. After some troubleshooting it is suspected there is no ignition. He replaced all spark plugs, still nil joy.
Then he removed all spark plugs from the cylinders and observed 2 spark plugs from the same cylinder while cranking the engine - no spark at all.
Could it be (highly unlike but possible) both e-mags are unserviceable or is could there be another fault?
Cheers!
