Cold... Very cold

Could be a crank angle , cam position sensor going. My beast did this to me last winter in deep river. Minus 40 and my truck was plugged in for 6 hrs.

 

Negative. Always RPM on the tach when cranking, no CEL, and after it fires it runs great and starts great after immediately shutting off and restarting. 

 

I guess this is pretty old and I haven't updated. The issue got a little better after re-popping injectors to 330 bar from 365.

 

I had a couple small fuel leaks. The issue was (is) air in fuel. I replaced every single fuel line and fitting from tank sump to VP inlet. Introduced a much better pre-filter strategy before my Walbro pump to cut back on possible air.

 

It's much better now, but the longer it sits, the more I have to crank to start it, especially when cold (-32 celsius last night). Still a bit of air getting in, very slowly. Not enough to keep the truck down, but enough to piss me off.
