If it is not your FICM or your oil filter/cap the only other things that I can think of would be to use some lower viscosity oil and check you battery voltage under load. Right now I am using 15W40 oil and I think that causes mine to crank slightly longer so at my next oil change I will probably go to a lower viscosity oil. Also, when was the last time that your fuel filters were changed?
