It seems to me that if it does not start, it will have to do if Gasoleo gets to the pump, if you will not have an air intake in the aspiration that has made the diesel be returned leaving air to be stopped ... it would have to be turned and loosen an injector to see if diesel comes out, if not; You will have to purge the injectors in this way, if Gasoil does not enter the pump, look at the "stop" electrovalve if it reaches the current or stayed or the coil of it is cut. The white smoke may be that it takes air in the aspiration line (from the deposit to pump) and that the injectors' pipes have air, or that the distribution is outdated (draft). As for the DTC bridging in an OBD 2 I am not aware that it can be done, in the ALDL if it is how the codes are removed per flash, but in obd 2 to pull scanner .. greetings !!
