The fuel rails are pressurized by an electric pump before you thumb the starter.

Usually no. You would have a lot of sparking at the brushes and eventually it would not turn over at all. Actually, the brushes are soft graphite and wear to make themselves shorter, so unless one fractured, it will still do its job until the carbon is gone and the spring touches the armature.What would happen if the brushes in the starter motor were worn or something like that? Would it be slow to turn over?
I know that, but it takes a couple of seconds for that to complete. If you thumb the start button before the FI light goes off, the fuel rails may not be fully "charged".The fuel rails are pressurized by an electric pump before you thumb the starter.

Well, my oil pressure light never comes on after the engine starts. Oil pumps make (enough) pressure almost immediately. I assume fuel pressure is up when the FI light goes out, maybe before, but I usually wait until it goes out before hitting the start button.I'm not sure about the cranking slowly part of your reply, but I don't think my ST cranks slowly with a fully charged battery, just a little longer than the C10 did when cranking it up. I can't say for sure, but I don't think my ST usually cranks long enough to prime the engine with oil, likely just long enough to pressurize the fuel rails. That is obviously not an issue with carburized engines.
I too have noticed that my ST13 Blue STar cranks more than I would have expected before lighting up. Obviously,, it is a much geared starter. But after putting in a new battery,, it did not crank faster,, either hot or cold. No big prob,, I just decided that's the way it is,,, and might be attributable to the function of the FI system. One other thing I will take notice of, is if it catches any faster after installing a new set of iridium plugs. Cat'
