Sanity Check - Where is the Fuel Pump Driver Module located?

[Bosnian Fiesta]

Chasing an intermittent fueling issue. Car would stall at speed giving the P0087 "Low Fuel Rail Pressure" code. Replaced the low pressure fuel pump, high pressure fuel pump, and EVAP system. Problem persists.

Looking at the other EcoBoost forums, some guys with similar problems have had luck replacing the fuel rail pressure sensor and/or fuel pump driver module. I've got a new FRP sensor on order, but I cannot for the life of me find the fuel pump driver module (FPDM).

I pulled the back seat & all the plastic trim from the b-pillars back. I pulled up the rear carpeting & sills. Pulled out the spare wheel & trim in the trunk. Jacked up the rear and looked all over the subframe. Traced the fuel pump wires but they all run to the main harness up towards the ECU. Web searches yielded absolutely nothing. If this thing exists, it's really fucking elusive.

Does anyone know if the 2014 Fiesta ST uses a FPDM, and if so, where it's at?

This is what I think the part should look like:

It appears to show up on the parts diagram (9D370), but neither Ford nor aftermarket vendors list it:

However, Ford does sell a pigtail wiring kit for it - WPT521:

And if ebay listings are to be believed, it is apparently installed on Fiesta STs:

So for the sake of my sanity - does anyone know where the hell this thing is or if it's even installed on our cars?

FML - right after I posted this I found out my library offers free access to the ChiltonDIY manuals. I've now got access to the whole service manual.

"The FPDM (fuel pump driver module) is located under the carpet and under left front seat attached to the rear of the front cross floor support in front of the left front seat."

Problem resolved. I'm an imbecile.

why go to the library when you don't have to? https://www.dropbox.com/s/s7wts7x85s2yu9e/2014 Fiesta.zip?dl=0

Lol badass dude thanks!

Luckily the library just gives you the password so you can log in online from anywhere. But having the downloads is way more practical I appreciate it!

No need....checked emissions Fuse#24 under the hood! It was blown....who knew that that fuse would cause such a problem.
