If that takes place though the motor is chilly, the starter will crank a tiny bit lengthier although the fuel pump builds ample force to start out the engine. In the event the engine is heat, the liquid fuel in the warm injector rail can evaporate, creating a “vapor lock” that forestalls liquid fuel from achieving the injectors.
