Are the spark plug wires replaceable or part of the ignit i on coils?

Steve:

Yes, the spark plug wire can be replaced, but you have to buy the ignition coil as the spark plug wire is hard wired into the ignition coil.

If the metal spark plug connector has disconnected from the spark plug wire, the connector can be replaced, but if the spark plug wire has been cut you'll need to replace the ignition coil.

If theres no spark from the spark plugs then you would have to replace them?

Inspection

Inspect for the correct routing of the spark plug wires. Improper routing may cause cross-firing. Inspect each wire for any signs of cranks or splits in the wire. Inspect each plug wire boot for tearing, piercing, arcing, carbon tracking or a corroded terminal.
If there is any corrosion, carbon tracking or arcing indicated on a plug wire boot or terminal, both the plug wire and component it was connected to should be replaced.

Removal & Installation

3.0L (VIN S) Engine

1. Disconnect the negative battery cable.
2. Unplug the engine control sensor wiring connectors from the ignition coil and the radio ignition interference capacitor.
3. Tag and disconnect the spark plug wires from the coil by squeezing the locking tabs, then twist the tab and pull upwards.
4. Unfasten the four ignition coil retainers and remove the coil and the coil ground wire the radio ignition interference capacitor. Save the capacitor and coil ground wire for re-installation of the coil assembly.
5. Wipe the coil towers with a clean cloth dampened with soap and water. Remove any soap film and dry with compressed air. Inspect the coil for cracks, carbon tracking, dirt or damage and replace as necessary.

To install:

1. Place the coil, capacitor and the coil ground wire onto its mounting location on the right hand valve cover.
2. Install the coil assembly retainers and tighten to 45-61 inch lbs. (5-7 Nm)..
3. Apply dielectric compound D7AZ-19A331-A or its equivalent to the spark plug wire boots.
4. Attach the spark plug wires to their proper terminals on the coil and make sure the boots are firmly seated so that the locking tabs engage.
5. Attach the engine control wiring connectors to the ignition coil and the radio ignition interference capacitor.
6. Connect the negative battery cable, start the vehicle and check for proper operation.

If there is a misfire, the cylinder that it is misfiring in will be recorded as a code in the computer.

Have the car scanned to determine which cylinder is bad. Then, replace the coil pack going to that cylinder.

Ignition Coil Pack Removal & Installation 2V Engine To Remove:

1. Twist the spark plug wires off of the ignition coil towers. Mark the spark plug wire positions so they can be installed in their original positions.
2. Disconnect the electrical connector from the ignition coil. CAUTION
   When removing the spark plug wires, a slight twisting motion will break the seal and ease removal.
   
   
   
3. Remove the mounting screws and remove the ignition coil.

To Install:

1. Position the ignition coil pack on engine.

I really hope help you with this (remember rated this help) Good luck.

check plugs wires for damage or just replace if you have replaced the #3 plug already if not replace it also
