Hard time starting the engine up?

I have an 05' Corolla that I bought brand new. It currently has 105,000 miles on it. The car has always been a bit hard to start. It has never not started but sometimes I will have to crank it several times before it starts. Othertimes it will start right away. Does this year car have a fuel filter that can easily be changed? And have you heard of others having a similar problem? I did take it back to the dealer years back and they said it was due to the 10% ethanol now contained in the fuel and they said there was nothing they could do to correct the problem.

Thanks for your kind comments sir. I will scan the codes as well.

I have the same problem with my corolla 2005
