I try to drive the car once a week. If I do that, it starts just fine. If I let it sit 2 or more weeks, it's hard to start from cold. I keep it on a battery tender so it cranks happily all day long, so battery and starter are just fine. After about 10-15 tries, it fires up, gets me to where I am going, and fires right up to get me home later that day, whether warm or cold. Will also fire right up the next day, or the next, etc.......only seems to occur after a couple weeks of sitting, like I said above.
Seems to me the fuel pump may be on it's way out. Is this typical behavior for a failing pump? Freezes up after a while from non-use, only to wake up grudgingly after a number of tries?
What say you?

Also, the fuel pump runs as soon as it gets power, correct? So it shouldn't require cranking to get pressure, like a mechanical fuel pump would.

The fuel pump only runs when cranking and when the engine is running. This is safety feature that stops the pump from running if the engine stops running, as it would with a ruptured fuel line.
