I dropped in a new engine, and first attempt to turn over the starter I got not response from the starter. What at a minimum needs hooked up to get the starter to engage? Since I had the engine out, everything was disconnected. I do not have the O2 sensors or the trans connectors on but everything in the engine bay is connected. I do have the 58x to 28x conversion box from Lingenfelter and I am getting a signal there. I am only at this point trying to prime the engine with oil thru the galley port and need to turn the engine over. I had a thought that maybe I needed a case relearn, but the security light goes out and I did not change the ECU. I do have a 08 SS block in an 06 SS but I am not sure that would make a difference. Is there something in the block that communicates with the ECU? Does the ECU know its not the same block. I know it's a stretch but I am just grasping for a reason. Thanks!
