I've never heard of that.

Sometimes if the battery voltage gets low the BECM and engine ECU loose sync with each other. It an immobiliser fault. You'll need a diagnostics system or something called a syncmate to re-sync the two.

Put your old ECU back in, ensure the battery is good, and re-sync the ECU.

Sounds like that's your problem. Where are you, there might be someone nearby that can do it for you. It only takes 2 minutes.

If the Omega EDC has not been put in secure mode when it was originally installed, then unless there is a compatability problem, it will start as it will not need the BECM sync.
