Question about 2005 Peugeot 405
If its a 2005 it will be common rail, so you have to be carefull when dealing with this engine. The common rail has extremely high pressures which can harm you, also the fuel injectors are capacitor discharged and are high voltage. Now thats aside, look at the high pressure pump at the front of engine. If the code on it ends in 018 then its fed by an electrical fuel pump. These fuel pumps can fail. if it has another number then the HPP draws its own fuel. The symptoms are air ingress into the fuel lines, causing the fuel to run back to the tank. Its probably worse in cold weather due to the contraction of the fuel pipes in the cold. Check all fast fit connections for security. A trick is to put grease on the connections, it wont last long but might give you an idea where the leak is.
