Parked overnight now truck doesn’t start.

[Redland1]

I made a delivery last night and parked next to the receivers yard.Went to start the truck and I heard a click but it doesn’t turn over.When I do turn the key I can see the fan on the motor move the slightest bit.Voltage on Insite shows 11.6.Also when I held the key down a little while I went to look at the motor and there was some smoke coming out of the power steering line in between the power steering pump and steering box.Any help would greatly be appreciated.
