Solenoid failure: Caused by excessive fuel return, WHICH is cause by dirty fuel and water. There is a little ball and seat that gets worn fast from lack of proper filtration. As most of us know, 2 mic filters were suppose to be run from the get go in 2002 when the common rail came out. Obviously Dodge knew a hell of a lot more than Bosch, and ran 10 instead.

 

X2 im fighting a lb7 with massive corrosion issues as we speak and have been for a while now.
Also worth mentioning the use of a alcohol based fuel treatment will ruin a common rail injector and pump with a quickness
