Update: Today I've been trying to start it, occasionally, and finally it warmed up enough outside to get it started. At first it stumbled and then after it got enough fuel/pressure it fired up. There was a little bit of stumbling, at first, but then it started running fine. No issues.
I'm inclined to believe it's the fuel pump. There's not enough fuel pressure when it's cold outside to open the injectors and get it to fire up. I've read that it takes 60 pounds minimum to open the injectors. I was measuring 58 pounds when it wouldn't start which is marginal and the shop also reached the same conclusion.
There is no tune up issues or anything else for that matter. Whether or not the gauge I used was accurate is another story.
Thoughts?
