Fuel pump 'arming' sound not present when ignition turned on. Bike will turn over but not start.
Hi and welcome to GS911 hexcode forum :)
Yes, it is necessary to check the output stage for the fuel pump (Fuel pump, electronic 16147720776).
Also measure the resistance of the pump motor. I wish you success
Thanks for the info update.
Yes, as Schuppi has said, the most likely culprit is the fuel pump controller. BMW Part number is "16 1 47 720 776"
