I had hot start problems with my 87 5KCSTQ that were finally diagnosed as
a non-functioning injector cooling fan.  Symptom was engine wouldn't start after
sitting for one hour, particularly at high altitude (I live in Colorado).  Less 
than one hour, no problem.  Cause was vapor lock from underhood temperature 
build-up and no cooling fan.  This was fixed by replacing the cooling fan relay.

After I replaced the relay, my fan seemed to run pretty regularly in the 
summertime, for a few minutes after shutting off the engine.
