A bad ignition coil on your Ford vehicle may a weak spark to the spark plug or no spark at all, making your engine miss or not start at all. Depending on your particular Ford model, the coils may come in one or two separate assemblies. You can remove the single assembly or the assembly with the bad coil(s) to replace the faulty component(s). However, pay special attention to the order of the spark plug wires connected to the coils; otherwise, you will disrupt cylinder firing order and cause engine operation problems.
Removing the Ignition Coil Pack
Step 1
Disconnect the negative battery cable using a wrench.
Step 2
Locate the ignition coil pack on your engine. If you have a 2.3L, 2.5L or 5.0L engine model, you may find two separate coil packs installed. Look at the front, upper and left hand side (drivers side) of the engine. Alternatively, just follow the spark plug wires from the spark plugs to the other end of the wires.
Step 3
Unplug the coil pack assembly electrical connector(s).
Step 4
Remove the EGR vacuum regulator solenoid from the coil pack mounting bracket if your particular model has this component attached to the coil pack assembly. Use a wrench or ratchet, ratchet extension and socket.
Step 5
Number each of the spark plug wires using a marker so that you know their exact position on the coil pack. This will prevent reconnecting the wires in the wrong coil terminal towers.
Step 6
Unplug the spark plug wires from the coil pack assembly by squeezing the locking tabs on each of the wire boots and pulling the wire off the coils’ terminal towers.
Step 7
Remove the coil pack assembly mounting screws using a ratchet, ratchet extension and socket. Some Ford models use a set of Torx screws to secure the coil pack bracket to the engine. Use a Torx bit socket, ratchet extension and ratchet to remove these screws.
Remove the coil pack assembly from the engine compartment.
Installing the Ignition Coil Pack
Step 1
Install the new ignition coil(s) on the coil pack assembly using the ratchet, ratchet extension and socket.
Step 2
Position the coil pack assembly in place and start the mounting bolts by hand using the ratchet extension and socket or Torx bit socket, depending on the type of screws used on your particular model.
Step 3
Tighten the mounting screws using the ratchet, ratchet extension, and socket or Torx bit socket.
Step 4
Plug the spark plug wires into their corresponding terminal towers on the coil pack assembly.
Step 5
Attach the EGR vacuum regulator solenoid to the coil pack mounting bracket, if necessary, using the ratchet, ratchet extension and socket.
Step 6
Plug in the coil pack assembly electrical connector(s).
Connect the negative battery cable using a wrench.
