In older cars, trouble with hot starts is sometimes caused by fuel seeping into the intake manifold caused by expansion of the fuel when hot and a bad needle valve.

How do you start the car when it is hot?

Since there is pressure in the fuel system, the problem could be a leaky fuel injector, (I have no expertise in this area, just brainstorming) or a pressure regulating problem.

I have read that if you hold the gas pedal to the floor when starting, no new fuel is sent to the engine.

If this tactic works, your problem may be flooding of the engine caused by heat.
