Rail pressure that rises and falls

[megamind]

In the area of cap usually c'? a small vent hole of the fuel occurs if ? clean why? also, what if ? attappato dirt leads to problems.

Yes, but I'm still undecided, why? of my friends, who have worked as mechanics, they told me that can? also be the dpf, therefore you are? I'm looking for and studying to delete the dpf, the egr already? done.

respect for all the ideas, but how can you relate the state of the dpf with the fact that the car does not start, or with the pressure dancer.
if the dpf has its problems, you can also remove it, but do not think of to resolve this anomaly

Hello, perhaps you have not read all the posts, but for the pressure on the dancer, it was the high pressure pump replaced and the problem is solved, for the hiccups ( let's call it so? ) c'? yet, but I see the turbine pressure that rises and falls, then pu? be that the ecu see a pressure too high exhaust engine and dpf and goes to cut the turbo pressure, making frequency the turbo pressure.

Guys, a bit late, but I want to say how I fixed it, I removed the valve of the geometry of the turbine, and the subsidiary finding of the water in the sponge that acts as a filter, to stay quiet reversed with that of the valve that is on the intake manifold, right now it's a fairy tale.
