Yeah, if there's no communication with the scan tool, it sounds like the PCM is shot. No communication with OBD-II is a typical sign of PCM failure.

Maybe a bit late for you - same thing happened to mine, with obvious power loss as well. Recall repair - "oil pump sending unit". No issues now - noticeable power improvement when towing.
