The ECU is a red herring - they won't prevent the engine from running - they are only there for feedback mixture control.

On an EA81, you need a few things:

1. Air
2. Fuel
3. Spark
4. Compression
5. Ignition timing

Which one don't you have?

If you have power at the coil and the coil ohm's out good (both windings), then it's probably the module. Ask in the wanted forum - I'm sure there's a lot of folks with spare's.
