2005 Expedition Hard Start/No Start

[farmboyinboxers]

5.4 2005 expedition has been "hard start" for last couple of months. ford dealer told me it was probably bad fuel on last oil change. now broken down. thought initially it was fuel filter, then fuel pump. now thinking it's more of an ignition problem. i have power to inerta switch at back of vehicle (last check point before it gets to fuel pump). any ideas of where to check next and any info of on-line manuals??

Let me get this straight.... You got an 05 Expedition that I will assume is still under warranty and the dealer can't fix your problem???? I had a situation where my 04 was having starting problem that was intermittent. I took to the dealer and they gave me the runaround about not being able to duplicate the problem or get a trouble code on it. They had my truck for two weeks and the service manager even experienced, he said once but they gave me the runaround talking about they couldn't just go changing parts and if they could not pinpoint the problem that Ford told them they couldn't do nothing.

Well I contacted Ford out in Michigan and a Customer Care Rep. dealing with my complaint told me that the service manager should have never told me that and because my truck was still under warranty, they should have made every attempt to fix my problem. Well needless to say, I sent letters to the president of that dealership and Ford Motor Company. I ended up getting truck back, still having the problem and took it to another dealership that diagnosed and fixed my problem in one friggin day. That dealership is in the same area as the dealer that gave me hell and they said that they get all of that dealership's customers because of their crappy service.

Anyway, they replaced my fuel pump; spark plugs, ignition coil and parts, and IAC. My truck no longer has the starting problem....

If you can turn off the key and then immediately start the vehicl with no problem it is the same thing that is happening to my 2003 expedition and the Ford dealer has not been able to locate the problem for three years. Mine will crank and not start. After moving the key from start to off and then back to start it will fire up and run. My Expedition now has an idling problem with 119,000 miles. I also have the 5.4L.

Mine just started doing the same thing about two or three weeks ago. Has 62,000 on it. Sometimes it starts immediately especially cold. After running and then sitting a little while it will crank a long time sometimes sputtering to a start. If I turn the key off and back on it starts immediately everytime. Once started it idles like new, runs great, plenty of power, etc (5.4L)

Ford tested the fuel pump, said ok and then tried to sell me a battery. The thing cranks just fine. They did an injector maintenance on it still does the same thing. I'm mad at myself for letting them catch me off guard and sell maintenance not fixing the problem I have esp warrenty still good.

From other posts it sounds like a fuel pump anyway. It either is not getting spark to fire or fuel to fire and since it does start and runs once started , I'm thinking fuel.
