Would have thought you would need correct ecu.

Have you checked all the fuses?

Ie ones under the steering wheel as well as the ones by the battery.

When you swap the ECU you will need the key from the same car the ECU came from.

Well, I am not convinced that your old ECU will be totlay toast........have you had a look inside for damaged and burnt tracks.

The most that could have happened is that the 0V tracks might be damaged or the 0V part of teh loom is fired so worth a good inspection.

Help always available here but also try 'Yahoo Catera Owners', which are closer to home, like the people here who are very good with Omega's the Catera site is very active again with some knowledgeable members and also good for spares .
