My 2009 n54 335xi used to crank crank crank before starting up, until a few days ago the car just shut off, and if you attempt to start it, it just cranks and does not start up at all,the car has not gone into limp mode and is not giving any faults, right now it only cranks a bunch of times but does not start up could this be a hpfp failure or lpfp failure?

Check the low pressure fuel pressure with mhd or something similar. It should be priming the line and holding pressure before you crank.
