My 2004 ford expedition will not start

This could be an ignition or security issue if it won't crank when you turn the key. You can try disconnecting the battery for a few minutes to reset the system but ultimately you will need a hands-on diagnosis. A good scanner would help too.

Check your fuel rail If you don't have fuel in it your fuel pump went out or your in-line filter is clogged Or you can spray starter fluid in the throttle body If it starts but then kills you not getting fuel
