Hey guys, its about 0 degrees here this morning, feels like -24. I went out to the truck this morning, actually started up very well. But there was a unusual humming coming from around the fuel pump under the hood and the FP on my Edge was stuck at 3psi, then 4, 5, and seemed to stick 6-7psi. Normally I have about 14-15. I cut it off because I didn't NEED to leave, and I just replaced the VP44 last spring and do not want to do it again. I am just wondering for later today and the future, is this normal? If I had left it warm up would it get normal or would I end up causing damage?

True. Depends on conditions of where you start.
