Thank you this is very informative. Actually, cranking within 10seconds of shutting down a warmed up engine takes far less time, about 3 seconds. But it still isn't starting as it should. There is definitely a problem. But yes, when the engine is warmed up, I shut it, and then start it up, it does take considerably less time.
