Should your scanner operate differently ie not be able to communicate with engine running vs engine not running and scanner working this would indicate? One major difference is the alternator is spinning putting electrical noise on the Lin and causing these scanner issues.

I don't think the engine running or not should have any effect on the scanner working or not. I often use it for live data, and that requires the engine to be running.
