Drove through very heavy rain yesterday and was 2 miles from home on a 300mile trip when the engine on this van quit on the CT Turnpike at 60 mph. I managed to coast off the interstate and get flatbed towed to my home. The engine started once since the stall but will not restart today. The P1233 DTC tells me that the Fuel Pump Driver Module is offline.
I have not yet checked voltage to the fuel pump nor fuel pressure. I need to get this service vehicle back on the road for work tomorrow and am willing to risk $85 on the readily available Doorman 590-001 FPDM. My problem is that I cannot for the life of me locate this control module on the van.

Anybody done this repair and know where to find the FPDM on an E350? There is plenty of info on this for pick up trucks, but nothing useful on Econolines.

 

Looks like the module is up under the van at the rear mounted on the chassis.

 

from what i read: The fuel pump driver module on the ford e250 is located just in front of the fuel tank right hand side almost inside the frame rail.

Here is a good video and he gives a link to diagnosing but it is a truck, not a van. perhaps some info will be similar though.

 

Thanks for the reply. It's not the same as shown on the F150's.

 

I saw the same E250 information. The front of the fuel tank is on the left (driver's) side of an E350 and inside the frame rail is where the fuel filter and lines are attached. I checked the cross member and right (passenger's) side frame rail and didn't find the FPDM. The rest of the F150 information is helpful.

Is it possible that my E350 is equipped without a FPDM even though the P1233 is indicated and the Doorman replacement is an exact match to the year, make and model? The lack of information on Econoline FPDM replacement makes me wonder.

 

Another site said it is under the spare tire. Can you locate the wiring harness coming out from the top of the fuel tank and follow it back to the FPDM?

According to FPG, your van does use a FPDM

Not that's simply not possible. The EVTM for your year shows that module so unless you have a "one off" or prototype 2004 E350 you DO have a fuel pump driver module. Not sure I'd want to go with a Dorman part but I tend to opt for the best quality parts.

 

Going with the Doorman part was a mad dash to save a day of work today. The Motorcraft part wasn't available to me locally on a Sunday. The parts counter at a nearby dealer opens at 8am, so today is a different story.
I will be back under the van today until I find this control module. Tracing back from the fuel pump wiring is the best idea I've heard so far.

 

If you go to the ford dealer, they should have a diagram showing the location..

 

The FPDM on a 2004 E350 is located on the driver's side frame rail (inboard), rearward of the driver's door and behind the fuel filter. It is secured by two 13mm nuts accessed from the outboard side of the frame rail. Two of three 10mm bolts on a heat shield need to be removed to r/r the FPDM. The engineering # on the OEM part is 4C2A-9D372-BA. I found no diagram that shows its location.

The crank but no start condition was not corrected by installing a new Motorcraft FPDM.

 

If you're able to find a schematic for the engine controls for your year and engine--that's where the entire fuel pump circuit is shown---you'd be able to trace the current. That's about the only way to know which part has developed an issue.

In the owner's manual is a fuse chart showing all fuses your van would have---your chassis should have a 20 amp fuse in the Battery Junction Box (under hood) that protects the FPDM, After that fuse is the fuel cut off inertia switch that might have opened or failed---check that it can be reset.

I'm completely guessing that if you have power back to the FPDM then the fuel pump itself has failed.

 

Looks like #13 in the battery junction box is the only fuel system related fuse. I already checked the fuel cut off switch and it was not flush with the top. I've never experienced one that was tripped and could only guess that recessed meant it was in the set position. Please advise if this is incorrect.

 

Press the reset button to assure it is indeed engaged. If it is then look for power at the switch's connector on the White wire using a back probe. If power is there find the White wire in the Fuel pump Driver Module connector. While you're at that connector double check the Black/Orange wire for continuity to ground.

 

Just came across this old discussion and was sorry to see that I never posted an outcome. The fuel pump did indeed fail and was replaced.

This E350 provided outstanding performance as a service vehicle until my retirement from business in January 2021. I traded it in in February of this year on a 2017 F150 and was impressed with the value it retained. It will be missed.

Many thanks to all on this board for the invaluable assistance through the years.

 

Good of you to post your follow-up!
