Been fighting this for a few weeks now, and decided to call the dealer, but those places scare me bad, especially when the guy told me he would probably need my truck for "a coupla days". I have the extended warranty, but I still remember the last time I took a vehicle back to the dealer....my 66 Mustang (yup...that long ago), and they wrecked it.
Here's the problem...once the truck is warmed up, I come to a stop, or restart it and pull it into gear, and you hear the engine laboring, she's blowing lots of black smoke, and it is a real pig taking off. Actually, if this happens on my steep drive, it won't even budge. Makes ZERO difference (not even in the sound!), if I mat the loud pedal and hold it there for a full minute.
From a stop on the LEVEL, it creeps away from the stop, gradually returning to normal. The EGTs climb 2-300 deg. higher than normal setting there and till you are up in the revs. If I select Nuetral, she revs to about 1500 rpm for a second or so till the excess fuel is burned off. If I just release the brake on the level, the truck slowly accellerates to about 8 mph.
There is no box or chip in the system. I just changed all the filters (NA
PA Golds). Boost seems completely normal once moving.
This is an intermittant problem. I don't see any real difference in mileage, it has been on two tankfuls, I have bled off some fuel, seeing no water.
The service tech said his best guess was the transfer pump, but from everything I am seeing, it seems like too MUCH fuel getting dumped in.
I really don't want to leave my truck there. Someone has got to have experienced this wierdness. Please.....some ideas? PLEASE!

 

How many miles? Not that it matters , just curious. Check codes first. Key on/ key off 3 times ending in the on position on the 4th - NOTE * not cranking. Next, check all the intercooler hoses. Make sure no leaks. Those are the first things. Many different sensors and things it could be.

 

It sounds like a possible leaky injector. They will need to do an injector test for sure.

 

I meant to mention.......NO codes. Spoke with 3 different service depts in the last few hours, mentioned that it just made more sense to me that it could be injectors rather than a transfer pump as the first dlr'ship mentioned, but the one who sounded the most knowlegeable said that a weak transfer pump WILL cause smoke. He also said that it will likely take out the injection pump in time. Shows how much I know.

 

Keep us posted on what they find. I'm kinda with you in that the theory of a bad lift pump would be the cause of "blowing lots of black smoke". It doesn't make sense that not enough fuel would cause a condition that usually indicates too much fuel for the amount of air entering the motor. However,,,,, I guess we will find out!

Good luck and I hope they fix the problem.

 

what about a bad wastegate? if it is stuck open you'll get lots of black smoke due to no boost

 

this is a friend of my brothers deal , but any info may help. he had and 95 ctd and hooked up to his new heavy three pop out trailer house and got about 80 miles from home huge black smoke . unhooked trailer and limped to dealer about another 80 miles away. replaced bad inj. all better went back hooked up to trailer house started back on trip . now he just drove it 80 ok. anyway hooked up to trailer drove sum black smoke back. went to dealer traded her in on a brand new one. took two days to transfer all the goodies and away on the trip new rig no smoke. sorry i don't have any better answer.

 

Do you have an exhaust brake? If so it could be sticking closed.

 

Are you making boost? Sounds like lots of fuel, not so much air.

 

I was thinking a boost issue. Blown hose, open wastegate, air filter plugged, rat in the intake...

 

Yup on the Boost...showing normal there. Nope on the Brake, and I am not sure if the 600 has a wastegate or not....probably does, but again, the boost is there. Also, this is showing the worst at idle when you drop it into gear... where you are not making any boost anyhow.
What kinda strikes me odd is that nothing is throwing a code. One service tech who was suspecting the transfer pump said that it will not throw a code, but the inj. pump will and that if this IS the transfer pump, it WILL take out the inj. pump in time.
I have treated practically every tank of fuel, but something I AM guilty of is that I have run down to the last gallon of fuel on several occassions, and as I now understand it, that heats it up, which in turn is tough on the pumps.

 

ABSOLUTELY DO NOT CRACK ANY INJECTOR LINES ON A COMMON RAIL WHEN RUNNING!!!! DO NOT EVER! These things have the capability of running 30000 PSI. Typically the pressure is 5-6,000 at an idle, but if the rail pressure sensor is bad or the FCA sticks it can run full pressure. Diesel fuel ( or any other liquid ) under that high of pressure can enter the blood stream if it hits you. THIS CAN CASUE DEATH!!! I REPEAT, YOU CAN DIE!!! If it is not treated quickly and properly.

 

Listen to this - it's true! Don't take the old approach of "Oh it's a diesel, I guess I can still do this...

Now; as to the original post, there are things we all get wary of doing, but in the end, you may have to learn to just trust some dealer, but do them a favor. Let one with a good diesel tech do thier diagnosis on it, document everything, and they should have it back running right soon.

 

oops. my fault. i schould have checked sig. agree with ^^^

 

Trust me on this one.........I had absolutely no intention of tapping into the high pressure.
Wow.....scanning this post for typos reminded me of a great line in a song that a racing buddie wrote: "Trust me when I tell ya....Don't believe a word I say". Is that a great line or what? Anyone know who he is?
