The fuel pump sound heard after turning on ignition but before starting engine, is a subdued but obvious hum from behind. It typically last one or two seconds before pump shuts off. In cold weather I often operate the ignition switch two or three times which causes the pump to run again and seems to better prime the system.
The other sound you need to hear is the immobiliser assuming it's fitted. This is a loudish click from a relay after you have moved the transponder fob close to the ignition switch housing. A warning light at top of dash that needs to to cease flashing confirms immobilistation has been removed. Sometimes it takes a couple of attempts.
Both these sounds/indications need to be confirmed before pressing start button.
