Injectors? Fuel pump? what is it?

When I shut my truck off (2004 6.0) it sounds like the fuel pump is running for 30 seconds after shut down. I asked the dealer what it was and he said not to worry, it was just the fuel being pumped back out of the injectors. I've never heard of this and nobody I talked too has either. Its very loud and it seems to be coming from both sides of the engine so... it he right?

Bikes, Babes and Booze. What else can I say...

I am surprised that the dealer didn't suggest reflashing the PCM/FICM/TCM to the latest level when you inquired. The sound you are hearing is the injectors buzzing. It appears your truck still has the very old post key-off injector buzz strategy programming. It was pretty shortly after, that Ford released a newer calibration called "inductive heat" to aid in cold engine startup and driveability. Just a reflash at the dealer will rid your truck of the post key-off buzz.

I have a sticker by the radiator with this code:

That must be the ficm reflash?
So do I take the truck in and tell them I want a new upgrade? I wonder what that will cost?

There have been NUMEROUS updates released since December of 2005, and yes bring it into the dealer to have the latest calibration installed. It flashes ALL three modules (PCM/FICM/TCM) whenever an update is released. Cost should be around what the dealer's hourly rate is.
