Is the security light on solid or flashing while you are cranking the engine?
Ok, the immobilizer has it shut down. There isn't any injector pulse which is why it will run on the starting fluid but not when cranking. You will need to have the dealer or a mobile locksmith reprogram the keys since you installed a new ecm and it will solve the problem for you.

If the security light is solid, the keys lost programming. This has to be the place to start as it won't run with that light solid.
Well, sometimes it can happen simply because you had a cell phone to close, or the battery disconnected for to long. Speed pass and some thruway passes will cause it as well. I just know as long as the lights solid it's not going to start. No way to bypass it either sorry to say.
