Cavalier Coil Pack Replacement
If a coil pack dies the car will generally quit and won’t restart, especially if the engine is warm. When first diagnosing the engine remove a spark plug and still connected to the spark plug wire, lay it on the engine. Crank the engine over and look for spark to jump across the plug. This is a 1999 Chevy Cavalier with a 2.2 liter 4 cylinder engine. The engine quit quickly and would not restart on this car. The next step was to check the 12 volt power wire that powers the coil pack. After disconnecting the plug and checking the wire, there was power to the coil pack. This eliminated the possibility of a fuse or the ignition switch.
