Hello, I am needing some help. I recently swapped a 2003 5.7 engine, PCM, TCM, harness and IPM. I am having a crank, no start issue. I am getting fuel at the rail and spark. The 4.7 did not have a security feature and the donor truck did not seem to have one either. i have already junked the truck so cannot get parts off of it. I was able to hook OEM scan tool on it, will not communicate with anything because PCM says it is a 2004 5.7 durango. Have any of y'all ran into this issue? Could it possibly be the interior dash harness is pinned wrong at the bulk head connector where it goes out to the engine bay?
