Please can someone help, I have a 3412E Heui and when I power up the MPD it

displays ERROR, and the engine will not start.  There are no codes showing.

Appreciate any input

The MPD is not programmed to just display ERROR.  There should be some additional information. 

If your engine will crank but not start and the display does not have any engine data, then you may have a bad engine ECM
