My Subaru Outback 2008 will intermittently crank but not start. This happens at nighttime, morning, after running the car fine all day, after starting it fine once in the morning then won’t start at my next destination. This has happened at least once every couple months. If the car rests 15-45 minutes it will start up again and I may or may not have a subsequent issues later. It’s very mysterious and every time I take it to the mechanic they can’t replicate the problem and so they don’t know what it is. I have had the fuel pump replaced a couple months ago (which it was running fine no problem until this morning when there was an episode) and also I’ve had spark plugs replaced about a year ago. Is there anyone that can shed some light on this topic? If it’s just a querk of this make and model and I won’t be stranded somewhere at some point I can deal with it. But it’s definitely concerning.
