I test the RCM relay, and as you all told me, hand pushing centered relay.
In each case, starter not launch.

Relay seems to be OK :
12V on one side of the relay. When we put the key, 3 relay move and one come back after few second (relay pump). I've got 12V on the other side of the relay after they have been activated. For me all seems to be OK in this side.

I have download service manual with all diagrams ... thanks for the documents.

I think I've RCM issue, but problem not come from this part (I 've got two with the car, one new from 2021 and test = same with both)

On the other hand, I do a test with Delphi diag auto.
I've got P0453 error = FUEL TANK PRESSURE SENSOR CIRCUIT HIGH
I will look if this error could stop launching.

Regards

Nicolas
