so I have a 2004 tiburon 2.7l 5 speed Canadian car. Was having random crank but no start issues and flashing immobilizer light. Tried all the easy stuff like crank and cam sensors and the security antenna. I also have a 2006 2.7l automatic American car that the engine is gone in. So I decided to take the key and ignition , the bcm and the ecu from that car and try it in the 2004 and it fired right up and runs like a champ. I noticed though that the immobilizer light does not even come on when I turn the key on probably because the parts are from an American car. And I now have o2 sensor codes that I never had before but the car starts and runs strong.

We have to have a mechanical and body safety inspection every 2 years but no emissions testing or anything like that. Had a new sticker put on it yesterday.

Someone told me they thought the Canadian and American cars may have different sensors but I’m not sure that really makes sense to me
