Need suggestion on what could be wrong

Need some input please…Car threw up a “P0300, P0304,305,306” meaning random misfire, I have changed all my spark plugs and coils. Also the MAF sensor just in case, car still will not start, anybody can point me in the right direction?

Missfires

So many possibilities: how did it get to this point? Clear codes and retry to start and then recheck codes. Any other codes?

ferraricare only thing that lead up to it was occasionally when I’d be parked idle it would die out briefly then kick back on. Just recently it turned into a rough idle then no start. If I try to start it turns like it wants to start but never turns over.

What does your hpfp readings say?

If not that, then injectors would be my next diagnosis or vanos solenoids
