[QUOTE="JTS, post: 1509264, member: 19391"] Valve in the back of the drivers side rail looked fine. Return lines are replaced, ran the LP pump several times, cranking i cant get it over 650ps. Was getting a high pitched squeal with the LP pump running, assumed it was air. Tried cracking the injector lines at the rail to bleed air, did 1 on each side, got a bunch of air out. Did that several times on each side until i was getting straight fuel. No change, still only seeing 650 cranking. But the squeal is gone. Volume control valve and pressure control valve both show 48-49% when cranking. Commanded rail pressure is 5900-6k. Low pressure switch status shows "NOT LOW" with the pump on, and when cranking. I havet pulled the fuel filter, but i dont hear it sucking air like if it was put in wrong. I've ran the pump and blead it for probably a cumulative total of close to an hour. What else do you check before you assume the pump isn't as new as you originally thought and that maybe it's bad? [/QUOTE]
