Hard Starting, Fuel Pump, What's That Noise (C900)?

Three questions below, but first, background. Typically, when the ignition key is turned on a C900 there's a short noise, like an electric motor, but almost a 'beep', which I always thought was the fuel pump. I've noticed on my 1988 900 T convertible that recently there often no noise. I kind of figured that since I upgraded the FPR to 3.0, replaced the injectors and fuel rail O-rings, the fuel pump didn't need to 'spool up' or something. However, on Sunday, the car wouldn't start (in a parking lot, with warm engine, but odd weather conditions) so now I'm wondering if there's a fuel pump issue. After popping the hood, fiddling with ignition wires, and cranking quite a bit, the car started.
Am I right about the noise? How should I diagnose the fuel pump? Are my performance modifications at a Stage I level likely to contribute to a hard-to-start situation?
