I am not an expert in this, but if only the engine was changed and all the electronics are the same, I would say no. The VIN or other identifier will most likely only be in the electronics.This isn't a VIN mismatch issue is it? Somehow the ECU knows it's not the same parts from before.
I'd expect the identifier to be in the ECU. The engine is just a mechanical thing with a bunch of sensors mounted on it. I don't think any of them have any VIN identifier.I am not an expert in this, but if only the engine was changed and all the electronics are the same, I would say no.

Just more proof that if it doesn't work plug it in. I'm happy to see this was a simple fix.Okay. An update. Transmission harnesses was tugged when I pulled the engine. Pulled a few of the pins from the plug. Alldata bulletin indicates the wires going to the transmission can cause a complete lack of communication with the ECM. pushed pins back in place and now I have fire. Just having issues burping the coolant system.
I just replaced the engine in my 2012 1.8 automatic Cruze. Everything went back in place like it should. I have power to the dash. But when I try to start it, I get nothing. I have tested all parts individually and all are good. When put on a scan tool I get U0100, no communication with ECM. I have checked all grounds, they appear to be good. Every thing worked fine until the engine quit.
I have read this is not the most uncommon problem when replacing the engine. But no one has given a solution.
Does anyone have an ECM pin out diagram, or know where to get one. So I can check for continuity.
