No start, but cranks

Huh. That's very odd. It ws running well after the tune until this happened?

If you jumped your car again does it start up? If I didn't overlook anything and you are not pulling codes, it is probably because your alternator is not charging your battery while running, or rather it's not powering your electrical system. So your battery is taking the beating and your car dies as the battery doesn't have enough juice to keep the car running, however, it can still crank the car but not have enough power to start the car.

Could be as simple as that, but dunno. Hope this helps and that it is something as small

That sounds like something worth pursuing. Put a voltmeter on the battery and make sure it is charged and watch the dash voltmeter to verify alternator is working properly. Might be worthwhile to have the battery tested under load.
