Raw fuel in the exhaust

[MaRce1o]

A friend of my just bought a 04 F350, the truck starts for about 15 to 20 seconds than dies. If you crank it again it starts and dies right away. Let it sit for a few and it will start like the first time and die again. I tried holding it on for a few extra second and the truck stayed on, but barely, a lot of smoke came out of the tailpipe and when I shut it off and hopped off about a gallon of pure fuel was leaking through the small hole on the bottom of the muffler.

Possible injectors faulty?

Definately some injector issues. I just had an injector fail last week. tons of white and sooty black smoke with a cylinder 6 contribution code but the engine would run with a slighty rough idle and a horrible "valve tap" noise drivers side. Have you or are you able to pull any codes? Sounds almost like one or more injectors is hanging wide open and either killing fuel pressure, high pressure oil, or maybe even both. I'm still learning exactly how these injectors work, so I'm kinda going on what little bit I've managed to understand about em

Ahhh I would say so. Ya need to fix that pretty quick before ya ruin the block, burn a hole in a piston, worse ya can hydro-lock and bend valves, connecting rods, ruin the crank, or sling a rod thru the block. None of which ya really do not wanna have happen.

I'll be at the truck later on today and will plug my scan tool in to see if I can get any codes.

Thanks for the responses

All right, I get no codes at all besides OBII Tests Incomplete.

How can I find out which injectors are bad? Take them all out and just turn the key to on?

It sounds like you have multiple bad injectors. If you have the time and ability I would pull the injectors inspecting the orings and copper washers as you went. Then bench test them or find a local shop that will do it for you. I know a shop here will do it and if you have to buy a new one they take the test price out of the price of a new injector. Also make sure you get new orings and copper washers for any injectors that arent bad for reinstall.

It sucks but its probably your best route unless you can get an active scan done. I just ordered an injector o-ring kit. Here is the link.

What is the ficm reading?

Maybe you want to try the diagnosing procedure in this link to figure out what injectors are bad. 6.0L Powerstroke Injectors

All right, the injector on cyl #1 was literally broken. Replaced it. Now truck starts and stays at idle, but still seems like it's misfiring and after about 5 to 10 minutes, fuel starts coming out of the exhaust again. Definitely a hell of a lot better though.

I have a Solus Pro Scanner by Snap-On. Is there a way to pin point the injector that is malfunctioning without taking them out?
