Vapor lock does not prevent the engine from turning when the starter is engaged.
https://en.wikipedia.org/wiki/Vapor_lockwikipedia wrote:Vapor lock is a problem that mostly affects gasoline-fueled internal combustion engines. It occurs when the liquid fuel changes state from liquid to gas while still in the fuel delivery system. This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor, resulting in transient loss of power or complete stalling. Restarting the engine from this state may be difficult.
