When you say 'cranking', do you mean the engine actually running?

Or do you mean cranking in it's correct useage, as the moment when the starter motor is turning the engine to get it to fire?

It sounds to me as though the engine was hesitent while running, then you changed the fuel filter, it ran for a moment and now won't run at all? And now the battery has been flattened, so it won't even crank?

I think you've not replaced the fuel filter correctly, its drawing air in instead of fuel, and you've flattened the battery.

Check your fuel filter installation (missing o-rings?), and recharge your battery.
