So I’ve tried reading other forums but it seems none fit my exact problem. I have a 03 6.0. It start having cranking problems. It would crank then immediately stall out. After 2-3 times it would fire up then run perfect like it always had. Then after not driving it for about 3 days it did again then finally turned over but ran horribly. Heard a miss, had a dramatic loss in power white smoking. Occasional black smoke. I got home and shut it off waited about 30ish minutes then attempted to turn it over it had a real long crank then it bogged down then slowly caught up and turned over ( it’s hard to explain hopefully someone gets what I’m saying) I took it around the block to see if I missed any sounds or signs and i had next to no power, I mean I had the pedal matted and I was doing maybe 20 miles an hour. Right as I turned into my drive she stalled out again. I got a p2290 code a couple of times. Any ideas? I’ve got it tore down to the injectors be cause one of my (so claimed) diesel genius buddies swore it was the injectors. Any ideas?
