2018 M2 OG Cranking not starting issue

Any ideas where I should check? Swapped battery and checked front and rear fuse boxes. Plugged scanner in and was getting fuel pressure (14kpa - is this okay?)

Car was in an accident however no bags deployed and the car cranks therefore ruling out the pyrofuse being blown.

Fuel pressure is really really low. My car retains ~98 psi with the car off, so your fuel pump(s) might be dead - likely the LPFP since the HPFP on these cars are pretty stout. So I would check the LPFP, and I suspect it is not allowing the car to prime the fuel rail.

I’m going to double check the pressure readings today, thanks for your comment!

Wasn’t sure what the normal pressure reading was, hopefully its that as it’s an easy fix!
