Each plug has it's own ignition coil. Remove the bolt from the coil and pull with a twisting motion. Be sure not to lose the spring inside the boot. If I remember right these plugs are 9/16. If you have an air comressor, be sure to blow any debris out of the hole before removing the plug.Don't forget the anti-sieze and dielectric grease when reinstalling. Hope this helps.

SOURCE: changing spark plugs

Changing the spark plugs on a 1997 Ford Expedition 5.4L engine takes patience. Remember to start this project on a cold engine! I started on the passenger side by locating the Coil over iginition coils and cleaned out all the old dirt using some compressed air. Then I had to disconnect the electrical connections to both the Coil over ignition coils and the passenger side fuel injectors. Once you remove the small bolt which holds the ignition coil in place, use your compressed air again to blow out the spark plug hole. After that, you will need a 5/8" swivel spark plug socket and various length extensions to remove the spark plugs. Take your time because there is not much room for your hands. Before installing the new plug, check the gap and use clean engine oil on the new threads. Tighten the new spark plug and reinstall the coil over ignition coil. Reconnect the electrical connection to both the ignition coil and the fuel injector. Continue these steps with all eight spark plugs. You will find the ones on the drivers side are difficult because of the fuel rail gets in your way. Have patience and use swivel extensions to work around the tight spaces. When you are done, you will have saved lots of money! Don't forget to replace your air filter, fuel filter, and pcv valve to complete your tune up.

SOURCE: 2001 ford expedition spark plug location

That's because they are hidden quite well. If you look at the engine, you'll see yellow plastic prongs (?) that look like spark plugs, but hook up to the silver tubing.  That's the fuel injectors.  BUT, right behind the yellow plugs, are black ones.  The black one is the connector to the spark plug.  The plug itself sits about 4 inches down into the block of the engine.  They are a real pain, and from what I can tell, you only have decent access to the first 2-4 of them, then they get too far back and start going under the dash (you'll see what I mean when you get there).

I have a 2005 Ford expedition I need to buy spark plugs and spark plug boots- are the spark plugs long reach or short reach?

All you really need to do is go to your local autoparts store (I prefer AutoZone, but whoever you like will work) and ask them for the correct plugs. they'll ask you the vehicle info (make, model, year, submodel, engine type) and you'll receive the correct ones. Can't really tell if either one necessary. What's your owner's guide say?

Can bad fuel injector damage spark plugs on a 2005 Ford Expedition? and if fuel injectors being replaced should less labor be needed for spark plug replacement?

A bad fuel injector can cause spark plug issues. If the injector does not supply enough fuel, the cylinder(s) without enough fuel will run hot, often damaging the spark plugs.

But your mechanic needs to make sure that the injector is the issue and not a fuel pressure issue from regulator, filter, or pump. Hopefully he/she has already done those checks.

As far as the labor cost being less the spark plugs wouldn't be removed during the fuel injector replacement. Even if they did, most mechanics won't cut the price. But if you are a regular customer it can't hurt to ask.

No start condition with my 2005 Ford Expedition. Engine spins but doesn't start. Have tried starter fluid. You can hear fuel pump start. Sounds as if there is not spark. Have checked all fuses and relays....

.Never use starting fluid you can ruin the engine fast.check all wiring to coils. get a spark tester pull a plug and turn it over watch for spark.

2001 Ford Expedition Blew Spark Plug, fixed that now won't shift.

On the trans you have a shifting module that might need replace just make sure that the shifting lever is aline with the mark on the shifting module.(Drivers side)
As far as the plug goes you can so thread lock tight to keep it in.

Are the fuel injectors on the 01 expedition easy to replace on my own,I am ok doing the filter, and is there a trick to changing the spark plugs as well?

if you look at the front of your expedition on the passenager side as well as the driver side you will see a rail on each side there is two screws on the side of the rail remove the rail and lift up and then the injectors pop out and for the spark plugs you will need a long bar and socket that go on the spark plugs and be sure to put some anti-seize on the new spark plugs before putting them back in and also make sure all of your o-rings are on you injectors before putting them back in also pickup a small pack of grease for them at the autopart store before you put them back
