Opel Vectra B, 2.0 diesel, is being repaired. Mishina arrived with a problem: it starts poorly when cold, and sometimes it doesn't start in the morning, it pulls poorly, and it smokes light smoke. The main reason for a diesel engine not starting when cold is an air leak in the fuel system. Diesel fuel flows back into the tank, and the starter turns for a long time and doesn't start until it pushes the diesel fuel back into the injectors. Having thrown a transparent pipe into the system, as well as a fuel pump bulb, an air leak was found in the area of the return from the injectors. Opel Vectra won't start!
