Sorry to hear about your truck, Buck. I have a similar problem now and then with my Jeep Cherokee in cold weather (not as cold as yours!), I think the fuel pump gets lazy. The daft thing is, it's got the pre-start 'diagnostic' system on it which, in the 'States and Canada, includes a pre-heater, even on the petrol-engined one like mine. But no, not in the UK! B****y B****ks!
Erich, just seen your post re the In-Laws. I feel for you my friend; my family are still trying to fight the aftermath of my Dad's passing, December '07. The home help got everything, and we're sure she 'rigged' it when my Dad was vulnerable. Can't prove it though, which is a bind. I'll say a prayer for you, and hope all works out well.
Terry.
