Is this true? I thought that the injector fan power came
through a relay that would only allow the fan to turn on when
some coolant temp signal OK's it and in conjunction with a
ground from the injector temp sender. If I hook up my injector
fan motor to a 12v source it runs. If I have the car running and
ground the sensor wire the fan doesn't always come on. Just
when the engine is very hot.
