Generally easy starting when cold and hard when warm can be a couple of things.
1. Fuel filter or fuel pump causing low preasure--check with gauge.
2. Fuel injectors dirty because EFI adds extra fuel to when cold--clean them.

the cleaner in the tank often makes it worse.

I don't think it is your fuel pump if it initially comes up yo
pressure when running.
