crank no start and frustrated for months!!
hey guys, new to the forums here. i kinda poked around and have been researching my problem via google and some forums since it happened. I bought a 2004 F350 6.0 a few months back. ran great, for weeks, then i noticed every now and then ever so slightly it would have a slight power drop when cruising, would happen intermittently at seemingly random times. at around 55 she would do a lil power lunge and shake till i throttle up or down then would stop, it didnt do this all the time but most the time. it was due for an oil change, but only by 100 miles or so(just by going off 3000miles or 3 months) same with fuel filters, they were coming up due. so, i hit a little mud, nothing big, was in and out in a few minutes, wasn't rhomping on it neither. get home. drove to store later in the day. i went out of town for 3 days, come home to my baby not starting. crank no start condition with no relevant codes thrown. new batteries were put in, i primed the fuel pump a few times letting it fully cycle, i returned the sct tuner program back stock, cleared codes, no dice. fuel reset is good, plenty of oil in stick, bro in law hooked up his diagnostic scanner(he is an onsite and fleet mechanic) everything reads proper pressures and voltages, ficm tested good at key on and crank with no drop from 58v(swamps upgrade) even swapped the smaller board in the ficm to test further) fuel pressure is 55-60 i think, and the previous owner upgraded the system to bigger lines and pump a while back. the injectors click for a few seconds when key is on, then they stop. no white smoke or any smoke out the stacks at all. i contacted previous owner (one of my friends) who said he in the last two years has done numerous fixes, new Hpop, icp, crand and cam sensors i believe, egr delete, and a few others i cant remember off the top of my head. like i said, the diag tool shows great numbers and pressures all within spec and still no dice. yes the oil is still fairly clean as well. all fuses are good, and i havent found any bad wires or chafing. any and all help is appreciated. im still waiting on the bro in law to bring his scanner back so we can go further in depth, but so far he said he would "be there tomorrow" going on 3 weeks now. my baby just sitting and im frustrated as all hell. i am mechanically inclined and usually do all my own fixes on all my past or current cars trucks and bikes, this is my first diesel ive ever owned and so far she a real headach. thanks in advance for any and all help.
