2005 Sentra hard starting (sometimes)

I have a 2005 sentra with 100k miles that has a hard time starting when the weather is hot outside. The problem started 6 months ago and then would go away then come back. I can get it started by turning the fuel pump on and wait 5 seconds and then it will start. Now it will take two tries of this to get it started. It appears the problem is getting worse now. Before I shotgun any parts at the car any body have any idea's. And also there is no ck eng light on.

It is leaking fuel pressure regulator of some internal fuel leak (fuel goes back in tank. Attach fuel pressure gauge and see how fast pressure drops down after engine is turned off.
