I have a seperate post regarding some weird functioning of the nav, radio, blinkers and on board computer

This morning, cold start, 35 degrees outside, the truck would not turn over
Code 0000 pulled up on the nav screen, I allowed me to scroll through it then the standard Accept screen came up and the X then started

Any idea on what my issues are

02 4.6ism 78k on the clock and indeed of the standard service has come due, oil change, etc....

please help
