1hz not starting or starting weak (1 Viewer)

Hello everyone
My 1hz does not start or starts weak when it is hot.But it starts rapidly when it is cold.
Fuel system (timing), the battery or what?

A 1HZ that cranks fine when hot but struggles to actually fire up is usually a sign of a flogged out injection pump.

Is the problem with cranking or starting the engine?
