OK, I just fixed the fuel pump problem with my 05 Expedition. I replaced the fuse box that contains the built in fuel pump relay. The relay is mentioned as a non servicable part in the owners manual-R303. To replace this relay, you have to replace the fusebox. I can remove the fuse box in 5 minutes. I bought the new fusebox at the Ford Dealer for $175.00 plus tax. There are 12 quick connect plugs and a 10 mm socket to remove the wire going through the firewall. Yes, this wire is removable after you pop the cover off of the connection. A 1/2 inch socket will unbolt the fusebox from the inside wall at the front seat passengers right kick panel. Two sockets are all the tools that you need.
This Expedition would not crank when cold, 60 degrees, it would crank.
There are two wires going to the fuel pump near the Left Rear tire. Key on,White is 12 v and black is ground. Make sure that the fuel pump is getting power or not with a test light. This can be checked at the module behind left rear tire, on top of frame. You can see it at the 2:00 position at the rear tire through the fenderwell. The plug is on the front side of the module. I had to lay under the truck to access this wire. A shield mounts the module to the frame. Two small screws hold the module on the shield and two more hold the shield on the frame.
Coming out of the fusebox is a Dark Green wire with a yellow stripe. This wire sends power out of the fusebox to the inertia switch to the fuel pump. If you have power at #12 fuse but none at the green/yellow wire, the relay is bad. This wire is on the top of the fuse box, towards the firewall and bottom left wire in the plug. Again, to replace this relay on this vehicle, you must change the fusebox.
Hope this helps.

Hopefully some people are still around on this thread.... I just had a similar thing happen on friday. Car died at 65mph (I won't get into the no shoulder on the highway because of the snow and my young kids in the car.... scary). Anyway, I had it towed to my mechanic who came up with codes
P1235 P1233 and P0191. I then had it towed to the dealer who says my problem is related to the throttle. My question is, what should I ask them to look for? Is there any possible way it is related to Customer Satisfaction Prgram 07M08 where they have the injector problems with the 05 Expeditions? Mine is an 05 Eddie Bauer.
Please help!

scotttique, I have since gotten my Expedition fixed, but I still monitor this tread. For my situation, it was fuel pump. My vehicle was down for a month until the dealership received my part by surprise 2 Fridays ago, but hey who's complaining. I have all the codes and numbers if you need them. Good luck and stay on them. I also contacted Ford home office, and the seems to get things rolling once they got involved. I had my kids in the car when mine broke down too....man was I pissed!

Hi drequet...by any chance are you in Las Vegas area? I think I might be stuck with your old EXP...please let me know if you left it at Gaudin Ford.

I also had my fuel pump replaced the first week of February, bringing my repaid total to over $1200, but it has not cured my Expedition's inability to start. At the end of February, another mechanic said that Ford had issued a service advisory that computer software was causing symptoms sounding just like mine. I spent another $200 to reprogram the engine computer, but no change at all. I am very pissed that I have had my problem misdiagnosed time and again, and no one can determine what is causing it. It cranks but won't start at any particular time. Less often, it turns over then dies within 5 seconds. My truck has been at various mechanics for over six weeks since December 1st or so. I can't even sell it until I get the problem fixed. Very frustrating.

I am currently dealing with a similar issue with my 2005 expedition. The truck died driving down the highway and i couldn't get it started again. Replaced the fuel pump and filter but the truck still will not start and the fuel pump is not running but does work. Checked the fuse and is not blown. it seems that there is no power going to the fuel pump for it to work. Please, any advice or expertise would be greatly appreciated.

i replaced my fuel pump and that wasn't the issue. Turns out it was the fuel pump driver module located in the rear of the truck under the frame. Terrible design by ford to put an aluminum driver module against the steel frame. My module had a hole eaten right through it due to corrosion. The module is basically the brains for the fuel pump and without it functioning properly the truck will not run properly. replacement part was just over 100.00. They are on backorder so be prepared to wait for a couple weeks. I paid a little extra to have my ford dealer locate one in michigan at another dealership and have it shipped in two days and the truck runs great. hope this helps. Hang on to receipt if this is the problem, I was informed ford may be recalling this defect.

As you can tell from my long series of posts above, I replaced BOTH the pump AND the module. Neither helped me.

No I did not leave it in Las Vegas! It is in Illinois - I see it all the time and wish I still had it!

My 05 Expedition has had continuous fuel issues. We already replaced the Throttle Body which would cause the engine to shut off randomly, placing my wife in danger trying to move the vehicle to the side of the road so she could re-start it. The NHTSA wanted me to send them my old Throttle Body because they have had several complaints on this. I also replaced my fuel pump twice, my mass air flow sensor, and now have to replace my Fuel Pump Driver Module because it has corroded. This 05 Eddie Bauer Expedition has been a nightmare. I also had to have the transmission replaced at 50,000 miles... My '97 Expedition was great.
