Ignition Cable: Service and Repair

SPARK PLUG CABLES

Spark Plug Cables:

The cables insulate the spark plugs and seal the top of the spark plug tube. A grooved tray routes the cables from the coil to each cylinder. The cables for the even number cylinders run along the bottom of the tray. Cables for the odd number cylinders run along the top of the tray. Access the cables through the openings between the runners of the intake manifold plenum.

REMOVAL
To remove the cables, lightly grasp the top of the boot with pliers. Rotate the cable slightly and pull straight up. To replace the cables, disconnect the cable from the ignition coil. Remove the cable from the tray and route the coil end under the center of the intake manifold plenum.

INSTALLATION

Fuel Rail:

To install the cables, run the coil end under the plenum and through the cable tray. Route the cables for the left side of the engine under the front of the fuel rail and then down the side of the rail. DO NOT PRY ON FUEL RAIL. Connect the cable to the coil. Slide the insulator into the tubes and over the spark plug. Ensure the insulator fully seats to the top of the spark plug tube.
