2004 EC450 crank, no start

I have an intermittent no spark issue. 12.4v at battery. Drops to about 11.5v cranking. Primary and secondary resistance within spec for ignition coil. 10v present at connector for coil when ignition on (shouldn?t that be batt. Voltage..?). When cranking .9v present at connector for coil when unplugged. Am I looking at a possible ECU issue?

Those bikes were plagued with electrical issues, most of which were due to the ecu connectors and the fragile thin wires that connect to them. I have never seen a faulty ecu for one yet. Sold about 5 of them though, despite me saying it won?t be the issue.
