2008 6.4 fuel problems
My 2008 f-250 6.4 is throwing 4 dtc codes which are p0088"fuel rail/system pressure-too high" p0275"cylinder 5 contribution/Balance" p1000"obd system readiness test not complete p2291 "injector control pressure too low-engine cranking". I cant begin to think what the problem could be im not a mechanic but i usually do my own work on my vehicles i previously owned a 7.3 so i know my way around a diesel engine so any suggestions would help out. thank you

Well, I'm not a mechanic either, but there are a couple on here and I'm sure one will give you more info in a while. The fuel system on these trucks can have some expensive problems. Based on threads I've read on here it sounds like a HPFP (high pressure fuel pump). Have you been keeping up with the filter changes on both filters? Very important and very important to use ford filters. Good luck.

If you got the latest flash and you don't have a wrench or a Limp mode then it may just be that number 5 injector. sennix will be here soon and decypher the codes for you. Do you use a fuel additive, most of the regulars on here use one. Diesel Kleen seems to be popular. that's what I use. good luck

Yup..HPFP. And an injector.
Either bad fuel with water in it or something. Be sure to gather your reciepts for the fuel filter changes and take that in with you.
Hope they were motorcraft filters.
