I assume you are talking about the ignition coil that is fastened to the top of the spark plug, and not sort of thread repair coil kit, like a Heli-coil, that has been used to repair the spark plug threads down in the cylinder head. To remove an ignition coil on a 5.4 liter, I clear whatever might be in the way of gaining access to the top of the coil, like heater hoses. On the very top of the coil there is a 7mm (9/32ths inch) bolt holding the coil down. Remove that bolt, and use a twisting motion to remve the coil up and out of the spark plug hole. Sometimes the coil boot will seize to the plug, and stay in the hole, while the coil assembly comes apart. In that case, use a pair of needle nose pliers to grab hold of the top of the rubber coil boot, and use a twisting motion to break it free from the plug. The boot can be placed back over the coil spring with no problem. If you rip the boot, new boots are available without purchasing the whole coil assembly at the dealer inexpensively.
beneath each individual coil pack. You need to remove a coil pack to get to a spark plug.

On the Ford Triton engines a separate coil is used for each cylinder. The coils are mounted over the top of the spark plugs. To access the spark plugs, remove the screws that secure the coils to the top of the cylinder heads and gently pull up on the coil to remove it and the short 3-4 inch plug wire that attaches the coil to the plug. A special knuckle joint or flex extension will be required to remove some of the plugs located at the rear of the engine. There are 4 spark plugs on the drivers side of the truck, four on the passenger side of the truck.
no spark from the coil, or the icm, or plugs are shot or plug wires, no fuel,no shark no start
