The past 2 mornings it's been about 37-39 degrees Fahrenheit. it's a 2001 Accord V6 3.0, it will crank and engine will try to run but dies shortly. It has a full tank pof gasoline, I thought it was a fuel pump so replaced it, it ran fine to my 45 minute trip to Walmart to test battery, it checks good. than drove back home, it's run through the whole winter which was colder. This morning it would not run. replaced alternator, but now it's 52 Fahrenheit outside and it ran okay, started weak. I have no idea if it could be the spark plugs, injectors, or what. it restarts fine once it get running. please help missed work for past 2 days

crap how do I delete this so I can move it to the right section? I'm too stressed out to think now
