I'm having the same exact problem and unfortunately I'm not very good at mechanic stuff. This started out of nowhere when I parked my car one day. The car will start up on the first try but if you don't hold the key down long enough or you forget the cars in first gear and accidentally stall it (like I did ) it's unforgiving and it won't start again unless you try basically the next day. After waiting for the next day it will start right up the first try for some reason it will not give you a second try. Or if you start it and then shut it off. It refuses to start again. Although I have one instance where I started it drove it for 10 minutes and then when I parked it again it started back up every time with no problem ; The next day I started it took my foot off the clutch forgetting it was in first gear and it stalled hense the name Noob. It refused to start again after that I guess I'll try again tomorrow.
This is the weirdest problem I've ever experienced with a car . I changed the spark plugs and the fuel filter thinking that was the problem . No luck
