(Long) Hot Starts....argh....

[Allen Swett]

Happy New Years,

Had a hot start situation just before Christmas on my 89 200q.  Thought I
had remedied the problem by replacing a bad thermo switch for the injector
cooling fan,
no problems for a week, now I have experienced it once more, now of course
I am about to sell the car.....So, once more I beg the wisdom of the list
in helping me solve this dilemma....I will be spending quality time with
Bentley in hand trying my best to diagnose all critical CIS
components.....Situation is such.  After car is fully warmed, and left
15-30 minutes, cranking cranking cranking, nothing...then it cools off,
starts right up.....Injectors are new, all tune up items are new, car get's
20+ mpg around town..... Vapor lock?  I would appreciate anyones insight on
their experieince with vapor lock or any long cranking issues...

Thanks in advance!
