Hey guys, I'm in a bit of a bind here. This morning and yesterday morning it got down to the mid 30's here in northern Louisiana and my truck refused to start. It usually starts at these temperatures and blows a ton of white smoke from the tailpipe until its warmed up. At normal temps around 3PM the truck always starts cold. It starts extremely cold and runs as if I'd started it in 20 degree weather while its 70~ outside. The oil pressure gauge reads normal when above idle but as soon as the truck hits Idle it drops down to no pressure. I understand that no pressure would stall the engine out, but I have read that the HPOP or LPOP can cause hard starts but I'm not sure if it's just the gauge. I changed the oil <1,000miles ago with new filter and the sort. This morning the truck wouldn't crank and I read 7 codes.


The glowplugs have been slacking off in recent times, as in <50,000 miles but they wouldn't cause the injector codes.
The FICM could be faulty but once again I'm not sure.
As for the Cam/Crankshaft codes, I have no clue what those mean but once it warms up I'm going to attempt to start the engine. I'll update if anything changes.
Thanks for any help and advice and sorry for the difficulty to read my scrambled post.
