All sorts of electrical activity when you open the driver door on this truck, just curiosity as to what all. Sounds at least to be high pressure fuel pump spinning up, among a few other systems coming on.

fuel pump priming and the truck 'waking up'

Want a good giggle? Dealer stated it was the tailgate unlocking.

Mine said the same thing. Clueless

With Forscan, you can turn off the fuel priming when driver's door opens feature. If you open your drivers door a lot with no intention of starting the engine, then you might find it useful to turn off this "feature". I found it a little disconcerting at first, but most of the time when I open my door, it's to drive the truck. So I'll probably leave it as designed.

For contrast, on my fuel-injected motorcycles, I always turn the ignition key to the On position and listen for the fuel pump to prime. Then I hit the starter. So in a way, there is some comfort to hear my truck prime up.

Is that the 'rapid fire' noise? I still can't make sense of that stupid noise. I doubt it's a fuel pump (2018s have 2), but could be wrong. I'd like to get rid of the 'rapid fire' noise, but need to know what it is first. I suspect part of emissions, but again, could be wrong.

Finally, for those who want to turn priming off, it'd be nice to know where in the FORScan Excel file is that instruction. At least on which module. Don't remember seeing that on the most common page. Thx.

Besides the fuel pump, I think the radio is getting a head start also, that's why the radio starts playing before the screen fully wakes up.

Where would that be? I did not see anything as I would like to turn mine off.

Is this on all engines? I don't think I've ever noticed this. I'll have to pay attention to it.

I have the 5.0 and have never heard it. Must be an Ecoboost thing.
