SPARK TEST



See Figures 1, 2 and 3

Because of the high voltage produced by the distributorless ignition system and to avoid overstressing the coil/module, an inductive or neon type spark tester should be used to check for spark. These tools are commonly available at most auto parts stores. Follow the tool manufacturers instructions to test for spark. Follow the diagnosis chart to check the ignition system.
