Replacing the ecm w/out proper diag would be a shot from the hip at this point. Does the engine start and run, and does the check engine light work? By the check engine working, I mean does it come on with key on, does it stay on when/if running? If you turn the key on, and press the 'off' button and the 'warmer(red)' button on the climate panel together, you will display codes at the fuel data center. E.0.0 will be ecm codes, F.0.0 are body codes. What are the codes displayed? It could be the machine that is not communicating with the ecm, you could have a poor ground, etc. Try this onboard feature and see if any codes display.
