so about a week ago i replaced the high pressure fuel pump and injectors on a 6.4 do to high amounts of metal shavings i found while replacing the fuel filter and a code that came up after it came in with a lack of power complaint i believe the code was a p0088 or something close to that now the truck is back together after the cab was removed i bled the fuel system and the truck fired right up after roughly 6 to 8 mins of idling the truck shut off and will not refire the wrench light comes on and the code that pops up is a p2291 fuel rail pressure too low i talked to a local ford tech and he told me it was the frp sensor so after a few more hours and some more money the truck still wont start any ideas out there im stuck scratching my head
the fuel cut off is not tripped and it seems to have plenty of fuel to the hpfp both the primary and secondary filters are full of fuel and i have bled the air at the fuel cooler like ford says to no avail im starting to wonder if i didnt get a bad hpfp from the dealership it is a reman after all
ok so after i got the cab back off i found the problem was a copper washer on the hfpf i replaced it and got the truck running now after several hrs of double checking and repairing i test drove it it seems to be runnin great but im now gettin a p0096 and a p3030 and the truck seems to take forever to shift and acclerate will no go above 55? any ideas?
