Title. My daily was running and driving fine, then I parked for a couple days, and went to start it and got this result. It's been doing this for about a week since, sometimes it almost starts but falls on its face. The fuel pump is working, I can hear the engine firing, the spark plugs are new, and the air filter is clean. It will not start on starting fluid, although I only tried once. The battery is good/being charged. There are no unusual lights on the dash. I'm pretty lost as to where to look, I guessed it lost compression but I have no idea why it'd suddenly lose compression to the point it doesn't want to start after running just fine.

 

Check the link from the FAQs sticky. you didn't mention checking spark, so I would start there if it were me.
