No, first of all I can't find the location of pressure regulator. And moderator say me that after 2006 they put regulator and fuel filter together with fuel pump. So now my car have hard starting when engine is hot.
Yes, I read the thread. I understand that you came in asking where the regulator is. My question was, what problem were you having that led you to think that you needed to find the fuel pressure regulator?
And how is that related to the hard starting when hot?
One thing that I'm thinking about is that the fuel system will also have a check valve in it to keep the fuel pressure up when the engine (and thus the fuel pump) shuts down. (I don't know the technical details on this year/model). If the check valve doesn't hold the pressure, then the fuel in the rail/fuel lines vaporizes. So on a hot start, the injectors are getting gas fumes rather than liquid gasoline. The result is a rough start.
If you want to check that, then next time on a hot start, turn the key to the run position - don't turn it all the way to where the engine cranks. Just to where all of the dash lights come on. Turn it back off. Then go to run position again (no crank). Do that about 5 times. Then turn the key all the way (to where it cranks/starts) and see if that gets it to start up smoothly. The goal is to basically prime the fuel system back up to pressure and purge the gas that has turned to fumes.
If that helps, then the answer doesn't change. The check valve is likely in the fuel pump, so it would need to be changed.
Of course, I still don't know what made you ask about the pressure regulator to begin with. And you can learn the same thing more accurately using a fuel pressure gauge (as mooseman suggested).
