It looks like most of the problems are with 05 Expeditions. I have a 99 with what appears to be a bad fuel pump. I have a fuel pump relay in the underhood fuse box that is OK. As far as I know I don't have one in the underdash fuse box. There is none noted on the fuse/relay diagram. My car would not start, but if you gave it a squirt of starting fluid it would take right off and run fine. this happened about 3 times in a month and then it would not start at all. I opened up the injection line at the fuel rail and there was no residual pressure. Not gas comes out when I turn on the key or turn the engine over with the starter. Sounds like a fuel pump to me. However, when I started looking for one, I found different part numbers for the 4.6 liter engine with std suspension, another number is it has auto adjusting (air leveling) suspension and yet another number for 4WD. I have the 5.4 liter engine with 4WD and 4 wheel auto leveling air suspension. Does it make a difference which fuel pump I use?
 
Any other ideas? thanks

I'd like to say fuel pump problem, but the problem is reoccuring.. I bought a 2000 Expedition, 5.4 E.B... Upon first driving the vehicle, with the key in position 1, (one turn foward, not cranking) the tach and speedometer, oil, all guages would all dial in the accurate direction, then back, then I could hear a constant hum coming from the fuel pump, or rear area. I installed a larger battery(disconnected power) and Zap, there goes the hum from the fuel pump, and after retrimming the idle, it no longer has performance quality acceleration , or transmission shifting, and the guages no longer set. I still run and start fine, but the 5.4 gusto is gone.. Is the constant hum the sending unit? I was told the guages set to indicate there is a trickle power draw. Only thing that doesn't work after changing the battery is guages and hum from pump.. Even if it is the pump, I'm thinking it's reference codes that get lost at power disconnection, not the pump. Even if it is tuner codes, it can be fixed without replacement, just tuner tool purchase.. Any similiar stories, definately want to chat,,,... EdBummer2000

#66 of 75 Full scale deflection on guages 2000 Expedition by 2000edbummer

May 08, 2012 (6:32 pm)

This is the technical term for the guages rotating all the way up, then back.. The theory is that this rotation signifies low charge or trickle charge in battery, an alarm or something. But more importantly I noticed that when this "rotation" was happening with the key in position one, I can hear 2 whirling sounds a second apart, then a constant whirl from the fuel pump, from the driver's seat. My charge was low, the battery finally died. I installed a new one, the guages "rotated", the 2 whirls a second apart happened, but no constant whirl upon 1st start up.
 That's when "deflection of guages" set in. No movement. Then a couple days later, no 2 whirls a second apart, no constant whirl before starting, and of course no idle or fuel trim anymore. I retrained it once but it seemed to go out again. Any ideas on how to regain that constant feed from the fuel pump, and retrim idle and fuel. ( Transmission recalibration) Not the 1st truck this has happened to. Hope it's not an tuner tool problem, if so which one!

Ok, I have a 2006 Expedition...Wed Nov 21, 2012 (day before Thanksgiving), I was getting on the highway, slight traffic up ahead, truck was up to 40MPH and just "died" I was in the middle lane, slowly pulled over but ended up stalling on a bridge and nowhere else to go but breakdown in the first lane on the start of a holiday weekend...UGH. Highaway patrol showed up 45 min later...pushed me into the breakdown lane and my tow truck came 10 min after that. Just got my truck back last night.....NOT the fuel pump, but the DRIVER MODULE...it was all corroted...my mechanic replace the module and the gas filter for $383?! I am hoping there is now a recall from Ford?! Or if this is something that should/could be possibly covered by warranty? Any information would be appreciated. I am just lucky my kids weren't stuck with me in the first lane on a highway!!

Fuel pump problems seem to be in all 2000- 2007 models. the one thing we all have in common is; there should be a constant whirl sound when you turn your key 1 time foward, but not started. if you don't hear it, your fuel pump is going bad, and fuel supply could stop at any second.. I'll be driving then all of a sudden the truck shuts down as if I've run out of gas, with plenty, and then it starts going again...

Doing a lot or reading reagrding this issue ( Also my problem ) this part Fuel pump Driver module has been the culprit on quite a few hard start's / wont start problems. The part can be found cheaply at around 60 bucks online to 120 and up elsewhere. The fuel filter about the same, double that amount for labor to install.
 I paid to have it looked at, they replaced the plugs, #2 coil, and a tune up and did not get the problem fixed, for 750 bucks!

I have reviewed all the posts that I can find to replace the FPDM on my 2007 Expedition but the part is not in the cavity from the spare tire. I am desperate to replace this part and have been unable to fiind it. Can someone please help.

I am having similar problems. I looked for the part online and could not find a fuel pump driver module. Could it be a fuel pump sending unit?
