Default Hard starts!

Sometimes, especially here recently, my car just doesnt want to start? I have an 03 gt with 38000 miles bone stock except for exaust. It always starts but sometimes ill have to mash that key turned to get it to! What could be causing this or is it just normal?

My car is acting like that right now. However I had a check engine light for fuel rail pressure sensor. I did searches on google and other forums and people said once they changed it out, the car started right up. I'm headed to the dealer this morning.

Does it not hold a steady idle? I.E. Reves up and then down?
