In my 1999 Berlinetta, when I turn the key, there’s a humming noise which sounds like something is getting filled up. Used to take about 15 seconds, now it’s a little over 20 seconds. Does this sound like a developing problem, as in the F1 pump, or is it something else? If so, where and how do I diagnose it? I’m not sensing any issues with F1 pedal shifting, though. Thank you all for your help.
