If you had had a EEC problem would you not get ENG CONTROL? Also if it was an incorrect valve position would you not get ENG FUEL VALVE?
ENG AUTOSTART is something of a catch-all message covering all sorts of start failures, not all of which are faults in the autostart system (bum igniters or possible engine damage a couple of possibilities). Further, ENG CONTROL and FUEL VALVE are Advisory, AUTOSTART is a Caution with an associated aural.
