04 no power, cyl contr. codes help

[timstrans]

04 f250, truck came in with no start, found low fuel pump pressure, replaced pump, now starts like a champ but no power on accel, truck will barely move, engine rough idle. getting codes p0246 p0278 p0284, all lh bank injector/cyl balance codes. any common issues if all contribution codes are on the same bank, or just a coincidence. ckd for mechnical injector/air bubbles in fuel canister and for wire chaffing issues no problems found. ran injector buzz test, all sound the same, no codes found during test. where to go from here?? thanks.

mine sounds the same but I have fuel still in the bowl. will not start and I think that having fuel in the bowl means that my fuel pump is good correct? checked for wires being bare and don't see any of them. have unplugged a ton of sensors(and plugged them back in) still no start but boy will she turn over!!!!! LOL
