Fuel Pump Driver Module

[dwhst9]

This is my 1st post in the forum, but I hope it helps others that have fuel pump problems...

We have a 2005 Expedition and the fuel pump died. Tried to order a new pump only to find they are on national backorder until mid-February. I found a used pump and had that installed. The truck at least started and ran, but still stuttered and missed. Turns out, there is a fuel pump driver module that is basically the brains for the fuel pump. I never heard of this before, but at any rate, here is where lies the problem:

The FPDM sits on the crossmember above the spare tire. Road grim, dirt, salt, etc collect on top of the crossmember and basically rot the FPDM. Take a look at the pic of the FPDM that we removed. The back of the FPDM is supposed to be solid!!!

Are you sure someone didn't cut a hole in that?!!!!! Damn...definately not the best place to put something that can't hold up to the road grime. Thanks for the heads up. I'll have to take a look at my '06 to make sure it doesn't look like that.

Yeah, not the best design and/or location. Apparently aluminum can corrode over time when in contact with steel. I did not know that.

1998 EB no Start

Thanks for the post. Do you know if this would apply to the previous generation of Expy's? (1997-2002) Mine won't start unless I add gasoline through the intake. Thanks.

I just took a quick look underneath my 97 (no spare tire at the moment) and there's no module on those crossmembers. There isn't even any space between the body and the crossmember for anything...!

Fuel Pump issues

My 2006 Expedition has been missing / stuttering severly. I took it in for service & they replaced the fuel pump. It's one week later & it's still doing the same thing. Now they say it's the fuel pump driver that is all corroded so they ordered the part. Did I really need the new fuel pump or was that in error?

I know this is an old post, but I found it while sitting at a repair shop in the middle of a 500-mile trip. I was travelling south in my 06 EB when it sputtered and died at 65 mph. I was stranded on the side of the road waiting for a tow. I checked my obd tool with torque pro and found that the fuel rails had lost pressure, and the computer was getting no signal from the fuel pump. A Google search gave info about this fuel driver being a common fault (http://m.ford-trucks.com/forums/showthread.php?t=1134339&styleid=20). I gave this info to the repairman who ordered and replaced the part in about three hours from the time that I had broken down.

There have been a few posts recently about this issue

I am on my way again, but my obd does not recognize the new part, and now I get no info from the fuel system. Any wisdom on this issue?

It's hard to tell. My 2006 expedition just died and it would not fire up again even though the engine was cranking really well. Mine was a corroded fuel module. It also had a hole in it.

It is worthwhile to check yours out before you're stuck in the middle of the road like I was & have to pay a toll truck and a mechanic to fix it.

It is visible from the rear driver side wheel well... bolted on the inside of the crossmember.

I did a write up on my experience with this on 1/13.
The moderators should make this topic a sticky,
because it's very common in severe weather areas
on both F150's and Expy's without older fuel return
systems. A little preventive maintenance and new
module will prevent the vehicle from being dead in
the water when you least expect it:

Removed the old Fuel Pump Driver Module. Knew right away that was the problem.
Kinda new to this forum, but I must respectively suggest this issue be made a Sticky. Better than that, hey Ford, HOW 'BOUT MAKING IT A SERVICE BULLETIN?
This thing looks like so many that I have seen researching the F150 Forum.
The F150's supposedly had more problems with corrosion being mounted directly to the frame.
On my '05 EXPY, it's mounted to a sheet metal bracket near the line of fire of the driver side rear wheel throwing road spray. Need to remove spare to make it easier to get to. First sign of trouble were the two 8MM bolts breaking off.
There's not even a suggestion of a fender liner or some kind of baffle to protect it. What's even more amazing is how much the force of the corrosion of the dissimilar pot metal pressing against this sheet metal bracket actually warped the snot out of said bracket. The rot hole that was formed meant water seeped through making contact with the PC board inside, and the oxidized powdered metal that also made it's way inside finally shorted the board out.
This module is the "brain" of your fuel pump, the thing that eliminates the return type pumps from modern injection systems. Ford could and should have taken a lot more care in where it mounted it and protecting it from the elements. I'm going to take further precautions, or, as my wife always tells me, overkill, to prevent this from ever stranding me. The Dorman's replacement that I got from Amazon- $58, at the recommendation of the F150 Forum, has two rubber isolators that keep it away from the sheet metal bracket and allow air circulation. This, and at a fraction of what it cost at Ford. I'm going to bed liner the metal part and make a flexible plastic "semi fender liner" to shield it from road spray.
I urge everyone who has this system in their Ford to check on it and replace/modify it so that it won't strand you like it did to me. And check it out before anyone fools you in going to more trouble and expense dropping the tank and replacing the fuel pump. Also, my experience shows that it doesn't always throw a code.

I will post this again to hopefully inform others that will ask.

The "Fuel Pump Driver Module" is only on the 2005 and 2006 model years

I have an 02 ford expedition and cannot find this module. Any Ideas?

If you read the post just before your post you will know why YOU can't find it on your 02 expy
