6.7 Problems Forum (2011-2016)
Bought a 2011 F250 with a damaged HPFP. Threw only one code p2291 (low fuel pressure while cranking).
FVCV was covered with metal shavings.
Changed HPFP, FVCV, FPCV, FPR, LFP , all 8 injectors, programmed IQA with ids, dropped tank and cleaned it.
bled the system by turning the key a few times...
