My car starts and runs great if it is cool outside. The past few weeks in
Seattle it has been in the upper 70's and 80's. Intermittently my car cranks
over and will not start. Then I wait and talk to it for a few minutes and it
starts. It has only failed when it has been parked in ...

I'm working on 1994 Saab 9000 turbo for a friend of mine.  Have isolated the
problem as fuel - complete lack there of that is.  This car will randomly
start and then go for a random amount of time 5 minutes to a day - and the
stop cold due to fuel starvation.
