What Causes Long Engine Crank Time?

Another common reason for long engine crank times is a vacuum leak. The engine vacuum must be a sealed system that the mass airflow and map sensors rely on to send feedback information to the main computer which, in turn, sets the stage for the engine cranking sequence.

Why does it take so long to start a 300K motor?

Of course, why not. On high mileage engines (200k to 300k) the piston ring can wear causing low compression which increases cranking time and makes starting difficult. This is because the compression ratio is low, and it takes time for the engine to gain enough speed by turning the starter to ignite the fuel-air mixture.
