hello, thanks for posting

Did this harder starting begin after the parts were replaced? Does it crank as fast as before or slower?

This engine requires iridium spark plugs, platinum should work as well but regular plugs don't work very well.

No, I have replaced those parts about 6+ months ago and I add 8k miles since then.
I get it as a use car (2nd owner).
I full like the gas line or the intake air may have something impact this issue.

Does the check engine light illuminate when the key is turned on?

Check engine light NOT turn on while diving.
It does illuminate when key is turned on.

Ok, what I would suggest then is to have the fuel injectors cleaned or try a can of fuel treatment, when cleaning the fuel system/injectors have the throtle body cleaned, too much carbon building up in the throttle body can cause hesitations and hard starting so I would go there first. Check all hoses from the intake air filter to the throttle body
