2005 F250 4x4 6.0L Diesel....What could cause injectors not to precycle when key is in on-position? Replaced FICM and had Ford program it. Still no precycle. Any ideas?
stiction, always use full synthetic like 5 -40 for oil side injector lube rotella is good oil for ford , egr gets sludgy sometimes also, some delete egr with kit , reg oil will missfire at start till warmup ,
the new flash may revise a no buz, full battery charge is a must 47 volt 45.5 at cranking .good oil pressure also
