Quoted: So at 173547 miles I'm calling it. I was able to change the fuel filters out just now and they didn't look dirtier than usual, but while looking into the fuel bowl if you really looked hard, I mean hard, you could see what appears to be some tiny silver specks in the fuel. So I am guessing the hpfp is dead Jim. Interestingly enough I had the same code pop up when towing and when empty, what's weird is when it happens despite clearing the code with the scan tool I can only make like 15psi of boost and my cruise control is out until I turn off the engine and turn it back on. What do you gurus think? http://i295.photobucket.com/albums/mm127/audiosolstice/08616CB2-E201-4EE0-B054-06761857F3D7_zpschfknbhk.jpg View Quote |

You can get a kit with both of them for around $2k. As you see any metal pretty much means the pump is done too. You're looking at close to $3k in parts, and those engines don't last like the rest of the oil burners.....I'd think long and hard about making the truck someone else's problem. |

The turbos should be good, when I don't build boost I don't get any fuel pressure. So like you said somthing isn't letting the pump build pressure. Is there a special procedure in cleaning the lines to the tank and hfcm? Also, do I need to send my injectors to get serviced? You really think I should trade her in? |

Also, I have had the engine deleted from emission equipment since 134k miles. So, that should help prolong the blocks life i'd imagine. When the turbos crap out, I want to go with a single kit. Should lower egt;s for towing. i'll start saving some coin, for a new block. I'll know I will need one eventually. |

Should lower egt;s for towing. i'll start saving some coin, for a new block. I'll know I will need one eventually. a couple of different tings can happen. the short list. pre mature bearing wear, rocker arm wear and lifter wear from fuel dilution via the regen process. some times the pistons crack because of the thin areas on the lips where the piston has a dish on the crown. egr leaks and hydro locks the engine. Most of those things I don't have to worry about since I removed all of the emissions crap. More than likely in the future I am going to need new lifter regardless and rocker arms and push rods. I have 3.73 gears and that means I am turning about 2k rpm doing 65-70. Good thing for me I only do 55-60 on my commute, but still the lifters seem to be a wear item. That's not that big of a deal though, because when that time comes I am going to put in some head studs and replace the body mounts. I really need to get my garage built with a lift. |

Emission deletes go a long way on those trucks, especially if you get rid of the dpf and converter...it can add 5 it so MPGs. I won't have anything to do with them anymore after getting a phone call from an EPA agent
I'm not familiar with the aftermarket HFCMs....the stock ones seem to last pretty well though, at least for stock vehicles. When it comes to performance upgrades I shy away from them as they cost us man hours almost every time we've messed with them. |
