Hello, to answer your question, the engine will probably not run. The computer in the vehicle is set up for the engine that came with the vehicle. Differences in cam timing, sensor inputs, etc.. could all cause problems. The swap is not impossible but you will need to get a computer/harness that matches the new engine.

Hello, I'm sorry but I don't normally do the live phone call. I only answer questions when I have a free couple of minutes as I work full time in a repair shop. I will be happy to answer any questions you have on here or I can open the question back up for another expert to look at. Just let me know which you would like to do.
