Hi
I am new to this site. I am looking at buying a 02 chevy it has a 04.5 or 05 engine in it. It has never started. I seen it has the orginal fuel module and the one from the LLy engine there. I was told it needed a new computer (ECM) and harness. Would that be true. Or Could the orginal 02 ECM be programed or flashed to the specs of the 04.5 engine. Or would I need to get a new ECM and doing so will it plug into the harness or would I have to do some repining of the harness or stuff. I am sure there is a lot of open ended questions here. Ask and I can try to answer. Just trying not to get screwed in this deal. Let me know if I am going the right way with this project.
