- Is it turning over on the starter ? To start a diesel needs about 300 rpm from the starter.
- is the key being recognised by the immobiliser. Leave the key in the ignition and open the driver's door, a warning message is usually given but if not it might not be recognised ?
- have you tried using easy start in case it is a fuel problem ?
- have you checked any live data during the diagnostic ?
- did it just not start one day or were there any problems before ?
