('81 245, Auto Trans, K - Jet)  I am pretty sure this is what is
happening.  The first time I turn the ignition switch on the result is
most normal stuff but when I when I turn it off, then back on, the tank
fuel pump buzzes.  Therefore;  if I first twist the key on, then crank
the engine, it turns over several times before it fires, but if I
switch it on, then off, then back on, and crank it over, the engine
fires almost instantly.   How can this be?  In my former MG, Jag, or
Lotus I would not have thought twice about this and assumed it was
supposed to be that way, but I can't think of any reason for this
behavior to exist, so I am wondering why a Volvo does it.

Also, if I drive a while, especially uphill 20 miles for an elevation
gain of 4300 feet and then leave the car for a few hours I will
experience a long cranking time upon restart.  It might be related to
the engine getting warmer than usual, not sure.  Perhaps the heat
pushes the fuel back down the fuel line?

I was parked on a hill at a stop light and became concerned as the
brake pedal gradually went all the way to the floor.  I just had the
brakes serviced by a reputable place (a former employee previously
owned my car) and the master cylinder was replaced so I was suprised.  
The calipers are also pretty new and the car does not drop fluids
(Since owning the aforementioned MG, Jag and Lotus I have  grown
accustomed to actually having to raise the hood to check if the car has
fluids, sort of a pain.)  After some testing it seems like I may not
actually be losing brake pressure.  The brakes hold, but the pedal just
sinks.  Is this possible?  Is it the booster?
