Answer 1

probably moisture

try this

turn over the car

then stop and wait one minute

then try again

This is instead of just cranking and cranking the engine. Let the little bit of gas you put in the cylinders have some time to vaporize.

Answer 2

Fuel pressure regulator bad replace it and problem solved. I am assuming it is a 4.3 liter only other thing that can cause that is a coolant temp sensor or fuel pressure low.
