Well like the title says I pulled up at the bank and the truck started to miss a little.. Fuel pressure was jumping from 4.8 to 5.6 and down to 3.0k and then went normal.. But went back to school and my friend open the door and I smelt raw unburnt fuel.. Turned the truck off and turned it on and my friend said it threw a small puff of white smoke.. Smelt like raw fuel and the temperature is around 28 degrees. I'm gonna pull codes off the mini max in a minute to see if it threw a code.. What do ya think it is?:fustrate:

did you replace the hpfp harness?
Yes sir.
Maybe you lift pump starved the hpfp. Might have a loose connection....
Maybe.. That's what I'm thinking. Got a fass fuel pump and it might have lost connection somewhere but I'm in the truck and it's running normal.. Besides a bad thermostat which I need to go get right now lol

you said you smelt raw fuel-any leaks under the truck at all? seems like a hpfp problem of some sort

Smelt oil and nothing out of the normal.. So I'm confused about this stuff.. Truck never makes it even an oil change without screwing something up LOL
But I can't complain because it still gets me places.

You would be surprised how sometime they just bend or completely throw a rod. Friends 6.4 just did it behind the bell housing explaining why he couldn't find the hole. Did this just rolling up to a stop sign iirc
