Strange temporary no start

[Bares, Vittorio]

Subject: 1990 200 Avant

Symptom: Drive for some significant amount of time, stop, turn motor
off, go into store, come back, turn ignition - lights come on but no
starter.

 

During this time the anti-vapor lock fan is blowing on the injectors -
once the fan stops blowing, turn ignition, starter engages - she starts
right up.

 

Is there anything related to the injector cooling fan wrt locking out
the starter?

 

TIA!
