Cold Start Detroit

Also, when did you first notice the smoke on cold starts?

 

Oh ok...but since you had it overhauled I'm pretty sure it's one of those two sensors or may be even both. The sensors are pretty cheap from Freightliner...I would suggest you changing those first then we can go on from there.

 

Why not just hook it up to dddl and see what the ecm is reading as far as sensors

 

It won't show sensor errors through DDDL because the voltage input and output must be out of range which will trigger a code then reflect there but I see what you are saying allan.

 

It will show anything that is reading out. I'm not talking about codes.

 

Yes I know what you are saying. But if the sensor is shaky, its going to affect what DDDL shows you because DDDL displays what the sensor is telling the ECM. Unless if SmellFunny measures the current outside temperature before cranking the truck then verify the figures with DDDL

 

My 14l blows tons of white smoke on cold start ups. I had it overhauled at a million miles and it still does it.

 

Check the same sensors i mentioned in the previous post...the same applies to your motor. Did you change the injectors with the overhaul?

 

Yes I have had many sets of injectors put in. I will check sensors
