(k1500 pickup) when I try to start when it is really cold it just cranks and will not fire. I have replaced the battery and starter and I am still having same issue. I also did a fuel pressure check and it seemed to be working fine.

If this problem is only there when really cold and the starter crank the engine over fast enough to start, try a new coolant temperature sensor. It is usually located right near the thermostat housing.
