Hey there yall, im posting this for a friend, he has a 2005 with a few aftermarket bolt ons... This is whats up, Started the truck in the morning an it let out a bit of blue smoke for about a minute then cleared, he jumped in an drove the truck didnt feel right an was puffing alotta black smoke when driving, also the truck is not chipped... So he replaced the fuel filter, an now it will not start... The bowl filter basin filled up... He has cracked 3 of the injecter lines from the firewall towards the rads, an told me that there is plenty of fuel pressure... Any help would be great... Thanks for your time...

i had a similar problem on a 6.5 turbo diesel......going up a mountain highway and she had no umpf behind her like she usually did and was pouring black smoke out. turns out my waste-gate solenoid was out. i replaced it and it was back to normal performance and no unusual smoke. and as for not starting. my fuel pump took a dive on me so i replaced it, the filter, and lines and she started right up!

dont know if that helps but worth a shot on my part haha

First off he should not be opening the lines while cranking the engine. The CP3 is capable of producing 26,000 psi while cranking and can cause 3rd degree burns or worse. There is no reason to do this when diagnosing any issue.

Know back to his problem. Most likely the fuel system is not building enough rail pressure to start. The only way to check this is with a scanner, after market gauge or digital voltmeter. It is impossible for some one to look at the fuel coming out of the lines and tell if there is enough pressure. There needs to be 2000 psi in the rail before the computer will fire the injectors.

The reasons for low pressure can very from injectors to a faulty lift pump or CP3. I would first look into the lift pump to see if it is putting out at least 10 psi pressure and flowing above 460mL/10sec. Though even if it is only putting out 5 psi the truck should start.

Codes are probably the easiest thing to check. I believe you can do the three key cycle trick on a 2005 to retrieve any stored codes.

Yeah i didnt think that it was such a good idea that he was cracking the lines either when he told me what was happening with the truck over the phone...haha

The three key cycle trick that you speak of is self explanitory or what exactly do you mean?

the common rails are a self bleeding system, if it had air in, it will push it out itself, the key trick is turn the key on-off-on-off-on, stopping in the on position over a 3-5 sec period without starting the truck the odometer will show the codes, then say done, and go back to the mileage.. sounds to me like the fca might be going bad... has he checked it?

Yeah i will try the key trick in the morning... What do you mean by fca?
fca is fuel control acuator, it controls fuel pressure from cp3 to rail to keep pressure in check, usually they can fail and will have same symptoms, also if number 1 injector fails the truck wont fire either, the timing process the truck fires off the number 1 injector and follows the process of 1-5-3-6-2-4, if thats out of whack it will cause all kinds of problems. blue smoke is also indicative of oil in the fuel, check the headgasket, coolant bottle, etc make sure the oil doesnt smell like diesel...

i cant find 2505 heres another list
Just in case anybody needs a quick reference, I found a complete(?) listing of the trouble codes for our rides. (not sure if these are valid for the new 6.7L trucks. sorry.)
