I can't figure out where this, or what is making this noise. I'll start up the vehicle, and for about 10 seconds or so I'll get a sound coming from the rear sounding like a turn signal flasher clicking, and then it stops. Does anybody know what that is?

 

I heard the same thing last night. could not figure out what it was before it stopped.

 

Could it be the electric fuel pump doing this until pressure is built up?

 

I expect the pump to be pressurized during the initial key turn when the injectors spray an initial fuel spray to start the car.
