Why does my car struggle to start when the engine is warm?
This problem is closely related to vapor lock. Hard warm starts can also be traced to a leaking fuel pressure regulator (FPR) or fuel injector. If the fuel lines are hot, under hot weather conditions and a hot engine, the fuel will have room to evaporate inside the line, creating a hard-to-start condition.
Why is a hot engine hard to start?
Most of the reasons by which a hot engine would be hard to start are based on problems related to the fuel. When the engine is too hot, fuel can’t circulate properly due to the way in which vapor obstructs it and therefore the engine wouldn’t start as easily as it should or it wouldn’t start at all.

Sometimes a battery will show 12+ Volts without load but the voltage will drop considerably when you crank the engine. This is due to one or more of the following factors: Bad cell/internal connection inside the battery. Bad connection to a battery terminal, the starter solenoid (either side) or the starter.
