OK, that makes sense; the siphon kit from HarborFreight is cheap and you could clean out your gas tank, wipe it out with some blue lint free disposable shop towels and see if there was any moisture on the bottom, water tends to pull up at the bottom as it was heavier than gasoline.
Then, its not a bad time to install a new fuel filter as well; you could open the gas line at the fuel rail, turn the key on and let it flow the fuel stream, for a little bit to remove any old gasoline. There is a filter screen at the pick up point on the fuel pump and I just cleaned it with some carb cleaner. Cleaning your throttle body would be a good thing to do as well; if the fuel pressure regulator was never changed, you could do that too. At that point, you pretty much have done a full maintenance routine, on your fuel system and you should be good to go.
Lastly, I would do a throttle body alignment procedure; as you may have lost your settings from sitting for so long with a disconnected or dead battery.
