I thought I had this one figured out but maybe not.
My '06 LBZ was left unplugged when I went on a recent trip away from AK. This I did on purpose but what I did forget was to disable the auto-start system. The auto-start has a feature that if the block gets to -20F, the truck will start and warm the engine up a bit (~30 of run time). I came back two days ago to a small mound of ice under the exhaust outlet and an indication on the dash of an empty fuel tank (DIC and gauge) plus the truck cranks, no start.
I headed into town, got 5 gals of fuel and re-primed the pump. Problem is, none of my symptoms changed. Do I need to add more than 5 gals?
Does this sound like it could be some other issue?
I'm in BFE AK with no scan tool (ordering a Diablo Predator today) and the "local" GMC dealer is over 100 miles away.
Any suggestions before I call for a tow?
Thanks
