Gentlemen- help please. Got a 98.5 2500. has 5.9 .only mod is bully dog. Just use it as a bull hauler, and it's a good one.. only has 225,000 miles on it! bought a few years ago, don't know if the injection pump has ever been changed...if I leave it overnight or a few hours, it sometimes takes a long time cranking before it will kick. If I shut it off and then crank it up within a few minutes, it will kick off just fine...usually. When it does, it runs like a top at idle speeds. Sometimes when hauling heavy load, it will lose power all of a sudden, and my boost will go to zero, then it will pick right back up. don't know if that's related, i've heard that sometimes that is air filter (i have to change them quite regularly as i do alot of dirt road driving). turbo is not siezed. have changed fuel filter and air filter twice. I can hear the pickup pump, but it just doesn't seem to be getting fuel. Do I just jump right at the injection pump? or is there maybe a fuel leak, or a crack in a line somewhere I can't find? i'm about to burn my starter up.... HELP!!!!
