Cold weather and zero fuel pressure??
Every time it gets cold (10 degrees and below) my fuel pressure gauge and edge attitude both say 0 fuel pressure. Why do they do this? Warms up outside and I have pressure again. Need some suggestions. Thanks

Is the electronics just not seeing it because of the cold or what? I have to have pressure because the truck runs fine. Stays between 0-3 idling.
