Car Won’t Start Cold

My car won’t start when it’s cold (once it hits mid 20’s Fahrenheit). Took it to the shop. They kept it for 2 weeks. Couldn’t figure out what was wrong with it. The mechanic seemed very frustrated that he couldn’t figure it out calling it “the hardest problem car he’s had in years.” I’m not a car guy so I didn’t understand a lot of the jargon he used while updating me on his progress. I’ve attached his “notes.” Anyway, I just don’t really know what to do. He gave me a break on cost of labor cause he couldn’t figure it out, but it still wasn’t cheap. I can’t really afford to pay another shop to end up just throwing up their hands. Any ideas on what could potentially be wrong would be much appreciated. 2010 Subaru Forester.
