Jun 5, 2010 - 9 posts - ‎7 authors I have an 06 Dodge 5.9L that has a light white smoke and rough idle when first ... 2006Ram 2500 QCSB 4x4, 3" Carli coils w/ 1" Daystar spacer, ... Still ran good tho, dispite the exact conditions you describe on Cold Start up.

take it to a dealer with a good desel tech may have a bad injector pump but they are very expencive so make sure thats the problem dont go to a side of the road shop with no idea how to test them

you have codes related to the pcm, transfer pump and a vehicle speed sensor. these could be related or all individual issues. related issued could be wiring, untill you start doing testing it will be hard to tell.
start cheap and test the speed sensor first, then you can clear the codes and continue on any codes come back.


Disconnect the PCM harness connector(s).
Disconnect the Vehicle Speed Sensor harness connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance of the 5 Volt Supply circuit between the VSS harness
connector and the PCM harness connector.
Is the resistance above 5.0 ohms?

Check injector pump timing, sounds like your problem.

Sorry you are having trouble.
This is a major under job. You did not specify the engine size.
A manual will be a great help to you but I will tell you the basics
Remove the exhaust from the head (difficult)
Remove the intake manifold(difficult)
Remove everything else connected to the head(difficult)
Remove head(easy)
Install new gasket (easy)
Put it all back together
I hope this helps

check for fault codes in both engine controllers..may have a camshaft or crankshaft position sensor fault

Have you tried replacing the fuel filter

its not real bad to do but u will ned to discharge the ac system so that you can remove the radiator the condensor and the charge air system from the vehicle

check fuse #9 in the fuse box for being blown or lacking power...if there is no power to the fuse it is possible the ignition switch is bad
