Help needed ASAP

[Got f1?]

I have a 2009 E70 with N52 (3.0SI). I replaced coils 1-3 and all spark plugs. Just bought this and coils 4-6 were replaced under extended warranty of the previous owner. The spark plugs were original. Car has 94k miles.

Since this, engine will crank but not start and occasionally sputter. No idea why. Any suggestions? I did plug in my Foxwell scan tool with BMW software and got misfires in cylinders 4-6 (original coils there). Cleared codes and they have not returned but still no start.

Problem solved: Coils don't fully pull in connector. Had to pry them on.
