Plug and play, but...

You also need the immobiliser ring from the ignition barrel and the chip from the key. Car pass would also be nice :y

The Maps are different between Auto and Manual (it will still work) but you can swap the Eprom containing the Map easy enough.

There are much more likely candidates than the reliable ECU.

The ecu was hard to communicate with vaux com an kept kick us out
Then all of a sudden it fired into life no fault codes or anything
02 sensor 2 is reading high an the values don't move at all

Crank Sensor (1) is normally the first culprit for non start or intermittent start on the V6's, or Transponder Chip / Immobilizer issue (2).

(1) Doesn't always throw a Code.

(2) Was there any flashing EML when trying to start car.
