Summer or Winter, the first cold start of the day is very rough. One cylinder fires. After five seconds, Two cylinders are firing, Five more seconds, Three, then Four, and eventually Eight. After Five to Ten minutes warming, first acceleration produces massive white smoke for as long as Two minutes. The rest of the day my super fine F-350 starts great even after being off for up to Four hours, and does not smoke at all. I'm hoping to make my truck's first start of the day much less remarkable. Thank you for your advice, Steve
Rough cold start, white smoke only when cold on 2005 Ford F-350 Super Duty
This article supersedes TSB 06-22-3 to update the Service Procedure. ISSUE: Some vehicles equipped with a 6.0L diesel engine may experience white smoke, lack of power, exhaust odor, surges, running rough, or no start when cold. These conditions are caused by the injector spool valve sticking internally during cold engine operation (engine oil temperature (EOT) less than 70 °F ( 21 °C)) . The concern is typically evident following a cold start after an overnight soak at ambient temperatures below 70 °F (21 °C). and may last 3-5 minutes or longer as the vehicle warms up. The concern completely disappears after driving and the EOT is greater than 150 °F (66 °C). This concern typically occurs on vehicles with greater than 15,000 miles (24,140 Km/h). ACTION: Diagnose and address any warm driveability issues or hard fault diagnostic trouble codes (DTCs) prior to performing this TSB. Then if cold driveability symptoms still exist use the following Service Procedure. SERVICE PROCEDURE This procedure includes a FICM calibration that adds inductive heating of the injector coils to locally heat the oil in the injector to normal operating temperatures very rapidly and keep it hot until normal overall engine oil temperature is achieved. This will prevent cold spool valve sticking on all injectors. Therefore, it will not be necessary to replace fuel injectors for the cold driveability symptoms listed in this TSB. Inductive heat is active in Key On Engine Run (KOER) mode below 2500 RPM. It is tapered out from 131-167 ° F (55-75 °C) EOT, and is fully deactivated above 185 °F (85 °C) EOT.

This updated calibration strategy is a greater improvement than the previous post-cycle Fuel Injector Control Module (FICM) software release that cycled the injectors after shutdown (TSB 06-22-3). This strategy will eliminate the need to post-cycle the injector spool valves, and as a result will also eliminate the need to perform the E-Series wiring modification. The strategy achieves rapid heating of the oil in the injector through inductive heating of the injector coils. The Customer Information Sheet that was included with TSB 06-22-3 is no longer necessary. Customers who receive this new calibration after previously having received the post-cycle calibration (described in 06-22-3) will notice the buzzing noise at shutdown has been eliminated. This is normal, as the

post-cycle is no longer needed with inductive heating. Additionally, for E-Series there is no need to remove wiring modifications that were previously performed per TSB 06-22-3. Unmodified E-Series vehicles will NOT need the wiring modification with this calibration. 1. Using Module Reprogramming: FICM menu in IDS, reprogram the FICM to the latest calibration using IDS release 47.8 and higher or 48.2 and higher. This new calibration is not included in the VCM 2007.3 DVD. Calibration files may also be obtained at www.motorcraft.com. 2. If the customer previously had the Post Cycle calibration, notify them they will no longer hear the injector cycling after engine shutdown.

There was also a TSB that suggested that it was also caused by poor oil maintainence procedures and I have been treating mine with an additive that attaches to and helps to remove oil deposits. My thoughts are that there could be sludge in the injector passages that are adding to the problem. Since my treatments began and the update was completed, my problem has been almost entirely eliminated and is getting better with each oil change.
The 6L diesels have water cooled EGR cooler that is known to crack and leak internally into the engine. It can look a lot like a head gasket. It would be a good idea to do a pressure test on the cooling system to rule out any leaks. I'm guessing water in the cylinders can cause a rough cold start for diesels if it has accumulated.
hope this helps
