You need to go through the basics first. Fuel pressure over 293 kpa. Injector pulse - noid or injector test light. Check multiple injectors for blink while cranking. Ecm turns on 4 injectors at a time. Spark at atleast 2 plug wires while cranking. You need to invest in factory service manuals paper, disc, or online. Ideally the French version used in Quebec Canada.

If there are no codes, then you must make sure that you have fuel pressure and spark. Does the fuel pump even run for 2 seconds when the key is turned to the on position?
Does it even crank? This is just the beginning of basics. If you can be a little more descriptive, we can help/

Hi and thank you for your help,
When the key turn ON:
-Fuel pump turn on, but the starter can't start; He haven't the order ignition.
-The interior light turn On, and the central control light up "service engine soon" and "asr OFF"
-The Stanger think is the light road order can't work but the turn light is right.
-The LCD centrale doesn't light up but "door ajar" and other light is ok.
I think problem is ground electrical but where ...; behind CCM ? or in the Module ASR ? ..
