Sounds like your firing!
Be sure that your crankshaft is not wet, oil coated, or just plain out needs replacing. I'm almost certain this would fix your problem.

Yes. You have to take the car to a ford dealer and have the new key programmed. This should solve your problem. Good luck.

I am experiencing the same issue with my 2001 expeditiion. Just curious... after the vehicle has been running hot for a while and you park and shut the motor, then it won't restart? Unless I wait for approx 1/2 hour when motor has cooled then it starts up. I have had mechanics check the fuel line and the fuel seems to "vapor lock". The fuel pump may need repaired/replaced. I am not experiencing and electrical issue. This is a fuel intake issue.

SOURCE: how to change spark plugs on a ford expedition

I recently changed them and it was a job when you have to crawl up and inside the engine area. But anyways, I started out by buying the E3 plugs, which don't have to be gapped and they do save a little gas plus increased in a little more power. (not much), These set me back $56. go with a basic motorcraft platinum or bosch platinum. I then removed the top engine cover, removed bolts for fuel rail and easily pulled the injector rail up (you will see to replace the o-rings on the injectors by some people, but if you're careful you don't have to.) This gives you the room you need at the back of the engine to remove the plugs. I started at the front by removing the small bolt holding the coil in place, then removing the the coil/wire with a boot removal tool. ( Again you don't need this tool, but it comes in handy at the back plugs). After removing the coil, I simply remove the plug, Apply anti-seize to the new one and install plug. I then apply Di-Electric grease to the inside of the coil boot to prevent moisture getting in. I then install the coil back down on the plug and tighten down and move on to the next.
1. you will need a swivel for the socket
2. you will need an extension, ( I use a long 8" extension)
3. Anti-Seize Grease
4. Di-Electric Grease
5. If installing a plug to be gapped it is .54
6. After installing, check for fuel leaks at the injectors.

It took me about 1 1/2 hours to replace all plugs and a dealer charges about $375. Good Luck if you need any further help get back to me and I'll help any I can.
