The injector fan only runs when told to do so by a temperature sensor on the 
wastegate heatshield. If this sensor is not working properly/broken then the 
injector fan will not work. To test if it is the sensor that is faulty you 
can remove the wire to the sensor and touch it on the wastegate heatshield, 
if the injector fan runs then hey presto its the sensor that is broken, if 
not then good luck.
