To change the spark coil pack on a 1998 Pontiac Sunfire with a 2.4 engine, first disconnect the battery. Then remove the coil pack and spark plug. The spark plug should also be replaced with the new coil pack for best performance. Insert the new spark plug, then the new coil pack being careful not to bump any of the many other electronic parts. Then reconnect the battery.
