had this td4 recovered to us no start. checked fuel supply from electric pump and seems fine(good stream of fuel) snap on scanner showing 3 codes, p1190 rail pressure control p1260 delivery fuel pressure monitoring p0190 rail pressure sensor data shows only 3bar delivered fuel press when cranking,also main inj time 0 and pre inj time zero. seems to point to high pressure problem any ideas how i can test pressure reg in back of pump or sensor on rail or hp pump?(dont have a scope unfortunately) vehicle just cut out when driving and not fired since. anybody ever fitted a hp pump on one of these do you have to remove timing gear? any help much appreciated.
