It also said do not release the key from crank position when it first fires but rather after it has fired definitively, maybe another second or so in my experience. This is quite a juggling act but after a couple of days it becomes more intuitive.

This backs up another post I read elsewhere where someone said they leave key in position 2 for 15-seconds before starting to purge vapors from the lines of a sort of "mild vapor lock," and claim they haven't had a warm start issue since. I use the manual's 6-second rule for expediency and use full throttle and in the three days since I began this procedure I have not had a warm start failure since. I am going to confirm my results further over the next week and report back.

I hate to say it, but I am starting to think that at least some of the hot start issues are simply out of ignorance about how the system works. I was certainly doing it wrong and I hope my admission of guilt will help others with this frustrating problem.

Please do let me know if this works for anyone else out there!
