Truck is acting dumb again

[ramonpowerstroker]

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:

A bent rod for sure.

 

[pog]

injector?

 

[ramonpowerstroker]

How is a bent rod gonna cause that?

 

[forcefed6.4ford]

I would suspect an injector too. Don't they throw a CEL though?

 

[ramonpowerstroker]

A bent rod for sure.

How can I just randomly bend a rod though?

injector?

I'm probably thinking it is my injectors I'm not forsure though..

Am about to check in 5 minutes. If it is an injector I pray it throws a code.

 

[ramonpowerstroker]

Got a couple of codes

 

[sootie]

what codes

 

[ramonpowerstroker]

P0087 fuel rail pressure low
U3f00 unknown

Wtf maybe a shortage somewhere?

 

[ramonpowerstroker]

Trucks got new hpfp and new rail pressure sensor so I don't know how it got low

 

[pog]

did you replace the hpfp harness?

 

[forcefed6.4ford]

Maybe you lift pump starved the hpfp. Might have a loose connection....

 

[ramonpowerstroker]

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

 

[sootie]

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

 

[ramonpowerstroker]

Looking under the truck and nothing.. But at the same time I think something gave I'm getting under the hood right now.

 

[ramonpowerstroker]

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.

 

[ramonpowerstroker]

*update*
Something blew up on truck... Oil all over the bottom and yea my trucks done more details to come..

 

[forcefed6.4ford]

Piston Buh Bye I betcha

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
