#49 of 75 Same problem - 05 Expedition won't start by i4get

Feb 08, 2011 (8:30 pm)

My wife's 05 Expedition (business vehicle) would not start Monday at 6:30 AM after running perfectly well all day Sunday. This vehicle has about 40k miles on it, no major problems til now. It has a new battery (< 1 year), but I put a high amp charger on anyway to show her it was not the battery. Thought the gas line might be frozen, put in some dry gas, still nothing. Called a tow truck to take it to the dealer, but figured it had something to do with the cold and decided to put a hair dryer on the fuel supply side of the engine. (All the posts on this thread are WINTER months). After 30 - 40 minutes it started up after a crank or 2 and kept running. So I canceled the tow and drove off - less than a quarter mile from my house it died. This morning (next day) it was taken to the dealer. They told my wife it will cost $480 to replace the fuel relay. This sounds reasonable if the problem is the fuel relay, like Capt. Toby (see post #25). I hope this does it - if the relay/fuse box cost Capt. Toby $175, then $480 seems reasonable with labor. I'm just scared to drive this vehicle with my kids in it after reading posts about other 05 Expeditions dying unexpectedly at full speed. I have copied your posts and will bring them to the dealership. We had planned to keep the Expedition another 5 years or more, but now I'm not so sure. Thanks to all of you for posting - this thread has been a great help.

Just had the fuel pump replaced on my '01 Expedition, after problem solving determined that it was getting power to the pump (indicating that the relay was not the problem). Only 100-200 miles since then, but so far so good!

So I've been driving around Los Angeles for 6 months with this starting problem. Sometmes it starts, usually it takes anywhere from 3 to 10 tries. Cranks over no problem then starts right up and strong. Sometimes starts right away. It's been a cold and rainy winter here - for L.A. and I noticed some improvements when it warmed up and got hot. Then it rained again and back to problems. So I took it to the dealer - $1100 to replace the fuel pump, fuel filter and relays - he said. I said no thanks, paid the $100 diagnostic and took it to Pep Boys where they checked the relay for me, (said he saw some water in the relay box) and anyway no changes by putting in a new relay (which he said would be about $10). He took it back out and didn't charge me a dime. So then I went to Econo-lube (it's now 6:30pm) and they change the fuel filter for $50 and showed my how really, really dirty it was. (Also changed the oil while I was there) Still, it didn't start up perfectly, but less cranks, 2-3.
So then I'm nearly empty on gas so I go to the Chevron and buy 6 gals of premium and a Techron fuel injection cleaner (good for up to 14 gals it says) and dump that in. It hesitates on start - but definetly better.
This morning I drove it to work, started on try 2. I figure maybe the gas tank is really dirty and needs some sloshing around cleaning. I get to work and turn it off and then on 5 times. It starts with slight hesitation on try 1 all five times.
I think I'm on to something here - so I suggest others give this a try. Change the fuel filter and clean your gas throroughly.
Also when I bought the car the used car dealership guy told me it took regular. I am hearing all around that is not true so I probably have 5 years of build up.
I will update this post if this doesn't work - oh and a fuel pump at Pep Boys is worst case $450 he said. The dealer was having to use after market parts so what's the diff? Pep Boys has fixed lots of my cars over the years just fine.
Oh and my brother pointed out that if it was the fuel pump - starting to go out - after 6 months wouldn't it be gone by now?

Have you tried turning the ignition to ON and letting the fuel pump pressurize the system for 5 or 10 seconds before cranking it? On some cars that helps 'em crank the first time.

It does take regular. Read your manual.

#54 of 75 05 expedition 5.4l problem with by scomo14

May 21, 2011 (10:00 am)

I just ran out last night about 5pm. At 8 am I went to start the truck and it just turns over and does not fire. I checked #12 fuse and the reset button in back and all were good. I do not hear the fuel pump kick on. What should I do to narrow down the problem . It has to be in the fuel system but after reading many post on here it could be 1 of 3 or 4 things in the fuel system. I dont want to go straight to the pump as it seems it that is the last thing I see people are doing . How do I know if its fuel pump or relay that is not making the pump work. Any help would be grateful. I have 86500 miles on it.

#55 of 75 2005 Expedition replaced corroded fuel module by i4get

May 22, 2011 (9:43 pm)

I had the relay problem - corroded right through. In January with all the snow and salt, I expect this issue is worse up north. but I got a lot of help and insight from this site. In desperation, tried a hair dryer on the passenger-side electronics against the fire wall and after 20 minutes, LO & BEHOLD it started! Then, like an idiot, I assumed I could drive it to the repair shop, and it died a block away - couldn't restart it, had no access to anything on the street like that. Had to have it towed to the Suburban Ford - our local MI dealership next day - my wife wasn't going to mess with it - it's her business vehicle - only has 45k miles. I talked to the repair chief about what I'd found out about this problem on Edmunds - also told him that I'd read here that there was a scarcity of replacement parts. They were aware of this issue and ran diagnostics - unlike some other posts here, where it took weeks or months to get it fixed, they figured it out and fixed it right away - My Ford dealer went all out, got it done in two days. I have kept the old part (6C2Z-9D372-A module) in case there is a recall on this - I may be able to get my money back. It is my understanding that they mounted the aluminum base of this module right on the steel frame - ideal for electrolysis and corrosion - mine is eaten right through - I'll try including a picture in my next post - see if I can figure out how to do it. Good luck!">

#56 of 75 Update: 2000 Expediton Ed B. 5.4 starting problems by sethtrucker

May 23, 2011 (11:39 am)

The improvement in starting has held over the weekend but the problem has not gone away entirely. Still, much better. Only a couple of cranks instead of 10. A guy at work suggested a new gas cap could help. My gas cap has been a little loose lately so I'm getting one at lunch. I am also trying the suggestion from our host Steve to
" turning the ignition to ON and letting the fuel pump pressurize the system for 5 or 10 seconds before cranking it? " and it seemed like it worked but I need to test it more.
Also the Ford dealer service manager is the one who last told me to use premium instead of regular. Not that I am suggesting he was entirely trustworthy - he wanted to replace the whole system!

#57 of 75 Four fuel pumps on 07 expedition 6mths by donm12

Jun 25, 2011 (8:24 am)

I have had four fuel pumps replaced on my 2007 expedition and was told that when replacing warranty parts they replace with remanufactured parts. The latest pump is new model and the old pump has the electrical wire in the fuel pump coming apart and finally breaking requiring a new pump. I am now on a new pump and hope this fixes the problem but not sure if there this pump will help. Leaving on a long trip next month and it seems the pump last 2 months. I dont have confidence that this is solved but I hope that it is. Owned Fords all my life and have never really had problems. This concerns me. Any help
