extended crank after sitting for three hours

This afternoon, my truck was parked in a field for three hours after being driven earlier for about an hour and a half. When I went to go start the truck after sitting it cranked an unusually long time before finally sputtering to a start. Once it started it had a cloud of smoke and then idled and drove home fine. Just wondering what could have caused this? It was cold and windy all day. If I were to guess by symptoms, I'd say something glow plug related but I'm not sure.

Did you watch your ICP/IPR values?
Ficm voltage logic/main pwr values?

Make sure you turn on the scangauge (red botton) before you crank on you starts to see if anything is out of the norm. Preset those PID,s into it

I programmed my ScanGuage to read the ICP and IPR readings today. Unfortunatly, the truck was already warmed up. When I started it cold this morning (ambient temp about 25*F), it started quickly but had terrible clatter and smoke until it warmed up. It hasn't clattered like that on a cold start since I started using Rotella T6 oil and Rev X. The next cold start, I will watch my parameters closer when I crank the engine. FICM volts have never fell below 47.5v when driving.

Watch the FICM when cranking next time. I'll bet the voltage drops quite a bit.

Just went out and started my truck after it sat all night. It popped off right away. It idled with notable "stiction clatter" for a couple minutes and a slight haze of smoke. The FICM volts didn't seem to drop below 46v. No DTC's by the way.

46 volts is still a bit on the low side ? What is the battery voltage running at, does that ficm voltage come up after the alt comes on a couple minutes later?
I know with my truck it's 47.5 at lowest but for maybe a second at most usually 48-48.5

Set up parameters on scangauge for IPR/ICP FICM main/logic watch all when you start.

I've only seen 46 volts during KOEO. I will watch the next time I give her a crank. I wish I would have had the ScanGuage set up right when it happend the first time. I read somewhere that you can get a FICM power supply half from International for like $150.00. Is that true? Then would I just have to swap the power supply, and not have to do any reflashing? Does anyone know the part # for that?

While cranking my truck this a.m., I saw FICM voltage drop to 45 volts. It started quickly but ran rough again like it has been on the cold starts. After it starts, voltage averages 48 volts and doesn't fall past 47.5.

Yea 45v is low, it's a matter of time before it fails on you.
Next question: what is the battery voltage when cranking and after it starts. If your down in the 10v range it may be part of the problem.
Moniter ficm voltage and trucks voltage.
If your battereies are hangin on replace them with quality batteries.

There is no need for reflashing the ficm, they are plug and play. There are different flashes for them as well as performance flashes that are available.
I see 47v once in a while for a second otherwise it's a solid 48-48.5

I haven't checked battery voltage during cranking or running. Both batteries were replaced less than two months ago so I'm doubting they're bad but I will check them out. Suprisingly, I think the batteries I replaced were originals (truck build date 4/2003), so they may have been stressing the FICM. Even if I don't always see FICM volts drop below 47 when cranking, the FICM is still most likely the problem right? It smokes more on start up now with more noteable stiction. ICP and IPR readings look good.
