Hey, I'm Twist...hope I'm doing this right it's my first post. I have an '03 F350 DRW 4x4 6.0 Diesel. I have little history on the truck as I bought it not running. It has 2 new batteries & previous owner told me the only code that popped was the ICP, so I replaced it & I soldered the connections not just those cheap connectors. Since the ICP replacement, it still cranks, no start, but also I couldn't see any smoke either. During cranking the one thing that I did see was that there is no movement from the oil pressure needle, it remains flat! I have fuel, checked & rechecked that. During cranking my oil resevoir is "empty". The filter seems to be connecting the bottom spring so that seems odd too me, also the filter was dryish when I pulled it to check oil flow. I'm leaning towards bad HPOP & looking at the kit to rebuild it, so long as the pump itself isn't done, but can use all the help I can get. The truck has new injectors, new rails, head bolts are done, new Crank Sensor, Cam Sensor, Fuel Filters, and has fuel in the tank.
