Car experiencing hard starts after parked for an hour. cranks for 3-4 seconds before turning over. Changed fuel pump assembly module in fuel tank, HPFP, injectors. still experiencing same issue. mechanic checked the fuel rail and said everything is fine there, including the fuel pressure regulator and sensor. There’s no visible leaks or odors.
What else?

Fuel rails are nearly the same. Look for the small device on the farthest endcof the rail from the fuel in from the tank. I can try to find one at lunch
