I just noticed that I can’t hear the transfer pump working, I just can hear the high pressure pump working
these cars do not turn those pumps on unless cranking or engine running.
there are 3 fuel pumps on these vehicles.
1: there is an intank lift pump
2: there is an engine bay high pressure feed pump
3: then there is the high pressure fuel pump attached mechanically to the engine like oilhammer said
pumps 1 and 2 are what you need to try and listen for when using a scanner. they do NOT automatically turn on when the door opens, or when key is ON in ignition. engine running / cranking is the only times those 2 run unless during diagnostic/repair with a scanner.
there may be a fault registered in the ECU for why it wont start when warm.
