Ok I don't know Jack about diesel, but i am learning as I go! It has been running out of fuel when the DTE is at 65-58 miles and its keeps climbing. When i first got the truck a year ago it ran out at 38 miles.... Now with that being said that is NOT my issue or even my concern. But what is the other day i ran out of fuel, put $30 worth of fuel in it, turns over but won't start. Just in the past 7 month i have replaced: (routine maintenance: oil filter, glow plugs, fuel filters) (non routine:) starter, throttle pedal, IPR, MAP sensor, ICR sensor, and exhaust pressure sensor. Its acting like it's not getting fuel but it is getting fuel. I'm lost as to where to go from here?? My only other thought is to really give it some fuel and some EXTRA heat to go with it!
