99 f350 cab n chassis died a few days ago wen it finaly started was missing didnt have any power changed the fuel pump to day still doing the same thing scanned it but didnt show any dtcs any ideas on wat to look at now

 

What color is the smoke? How much fuel is in it? How is the oil level?

 

White/blue smells like strait fuel full of fuel and oil

 

Did it start after filling it up? Does it only smoke like that when cold or all the time once it warms up a little? Hate to ask so many questions but trying to narrow down some possibilities since no codes.

What kind of scan tool did you use?

 

It started doing it wen it started gettin in the 50s at night would just smoke after startin in the mornings then it started doin it wen i would leave it idling wen i ran nto a store or sumthin basically after i had the fourth tranny rebuilt for it 2 months ago is wen this all started

 

Innova 3110 scangauge

 

4 th tranny rebuild? How many miles are on it? When it cranks cold outside, does it do it fairly easily or do u have to wind on it some/plug it in?

With it smoking white smoke even at operating temp, it would make me believe that you need to either check compression on cylinders or injectors. I had one that did that and it needed injectors. I think a lot of bad fuel went through it and killed them. It still smoked when warm but had plenty of power. I am assuming you are not using any fluids-oil/coolant and that u are running straight diesel.

Thats just my opinion though. There will be some others come along soon.

Does it skip when running at operating temp? Do u ever get a check engine light?

 

22500 on it if i forget to plug it in i cycle the key four times and she fires right up not using any fluids never had the check engine light and yes it misses sumtimes at operating temp along with the smoke

 

I usually change the fuel filters at about 7500 miles

 

225000 miles on it

Thats a pretty good link that Tugly found for that stuff.

Sounds like there are possibly several things that need to be ruled out.

1 is the GPR functioning? Will not account for the running warm but will for the cold starts.
2 check glow plugs for the same reason
3. Check the UVCH harness for connection and possibly doing the 50 cent mod if needed.
4. check oil discharge from injectors with engine cold and when warm.
5. If nothing found wrong before then, check compression

6. I know fuel pump is new but may be a good idea to check fuel psi as well to rule out restriction in the tank.

Springer pops list will get u through how to do most of that and/ or a quick search.

4th tranny rebuild? i had a 99 f250 that went through 2 trannys in 6 months and it was because the computer was bad under the fuse panel, it was taking out everything, hows your coolant pressure? leaking any? and the fuel these days just kills these motors, low sulfur fuel is horrible for motors, thats why i only run off road fuel in my truck, its full of sulfur and has way more oils for lubrication, works like a charm prevents a lot of problems, you could have a bad injector like the other guy said, could be dumping way more fuel then it should, do an injector buzz test and read the response times on each injector, i also have seen and exhaust valve get shoved through causing it to smoke like crazy and idle rough, is the power there? or are you losing power since this happend?

 

All this truck runs is off road fuel lol andshe has no power wen it does start and run it acts like its got a big cam in it loping the tach jums from 400-1000 as far as the tranny goes its had 2 remans and now the rebuilt i had a major electrical short and shortly after the tranny ate itself

 

I ment shortly before it ate itself

 

Mine had lopEd like that before and the ICP sensor was shot, I would do an injector buzz test to try an rule out the injectors being an issue, we own 5 1999 and 2000 7.3 and are all great, never once had injector or any cylinder or major motor problems and all over 200 thousand and were worked, and you have no codes when plugged in? A bad injector dumping to much fuel would cause it to lope because it's flooding itself, injectors are easy to do on that motor so that would not be to bad if you could test them and see before pulling them or pull the valve cover off and run the motor and unplug each injector one at a time until you come across one that you unplug and it does not affect the motor besides losing the lope
