Extended crank, then no start. PUZZELED
So my 04 was running fine until a couple of weeks ago. The temperature in my area started getting colder, maybe 45 degrees at night. I started to notice there would be a small period of extended cranking and a small amount of white smoke, most likely unburnt fuel, when the truck sat for a day or two. It didn't bother me and the truck ran fine. Then aroun last week the weather started to get colder, high 30s at night. The samestarting problem just a little longer crank time. Yesterday it was 29 and the truck sat for maybe 8 hours and it would not start what so ever. It would crank but not turn over, I tried about 8 times and clouds of white smoke poured out the whole time I would try to start it. So I proceeded to plug it in, of course 15 minutes later it started fine with some unburnt fuel(white smoke) coming out of the exhaust until it warmed up.
The glow plugs have been changed about 1000 miles ago so I have not checked them yet. The GPCM must be fine as I have no CEL. I also checked the FICM and had 48 volts with the key on and 48 volts with the engine running. It does not sound rough at idle and the injectors seem to be firing like they should.
So I have no idea what it could be. I am completely PUZZELED! Any ideas or suggestions would be greatly appreciated! Thanks!
