Over Fueling, No Power, new injectors and complete High Pressure fuel system

08 with 201k on it. Its WAY over fueling at an idle and has no power, you give it throttle and it cuts out and blows blackish blue smoke. I bought the truck this way, former owner thought it was a plugged dpf causing it so he cut it off but couldn't afford a programmer so he parked it. Anyhow I got a programmer for it and loaded a dpf delete tune but there was no change in the over fueling. Took it to ford put it on scanner there were no codes in the system, compression on all cylinders was good etc. They couldn't find anything wrong with the truck that was causing it to over fuel and they concluded it had to be the injectors were bad. So I replaced the injectors, in the process I changed fuel filter and there was a lot of metal in the bowl. Consulted ford and they said it was a bad high pressure fuel pump and the metal went through the system which is what caused the injectors to wear out and over fuel the truck. So without firing it up and chancing destroying the new injectors I changed out the complete high pressure fuel system, lines, pump, cooler, rails, etc etc etc just like they do using all the same parts as a warranty job. Got it all put back together and fired it up, same damn symptoms it had before, still over fueling and no power and still no codes. I am at a loss, Ford is at a loss I am ready to burn it to the ground. Anyone have any ideas? Thanks

what tuner did you go with? If it is a spartan or H&S, you can read ICP or rail pressure.. I'd be curious to see what it is at idle... did you install a new FRP sensor with the upgrades/swaps? What kind of lift pump are you running? the HPFP should be capable of returning the excess fuel, but if you're overwhelming it, it stands to reason that would overfuel the thing, too..

Programmer is an sct. It has the factory pumps is all nothing aftermarket other than the tuner and dpf delete. A new sensor was installed as well.

pull a p/n off the HMFC and compare it to both a 6.0 and a 6.4's... they look dang close, but produce big differences in pressure..

6.0:



6.4:
