Scan for codes and check fuelpressure first.

I check the code, but no code
and the fuelpressure is normal ( the mechanic said )

Have your crank and cam sensors checked for resistance they may be high and won't start well when warm.

In this condtion when the resistance of the crank and cam sensors are high, what should I do?

If they are to high then when the engine gets warm it causes hardstarting. I dont' have any specs howeveron what they should be so you'll have to check againsta new one like at anauto parts store. If they are to highlike out of range of a new one then replace them

Check fuel pressure should be 54.3-55.4 psi and hold it for 5minutes, if it drops slowly then one of the injectors may be leaking if it drops fast you need apump because the regulator is shot or bad. I have no other suggestions to give you other than your sock in fuel tank may be clogged or the fuelfilter itself
