Si el timing esta bien, y la corredera de la bomba tambien....
Hay que comprobar que no pille aire el sistema de gasoil, y que no le falte gasoil.
¿hace mucho que cambiaste el ultimo filtro de gasoil?
Mira con el coche arrancado, los tubitos que van a la bomba, si son transparentes, mira que no pase mucho aire, algunas burbujas es normal.
