This is the easy way if you don't have a tester. MAKE SURE you are NOT touching the plug or wire while cranking the engine over or it will give you one heck of a Shock.These vehicles are notorious for having shared ground wires that crack or rot and give poor connection to the PCM (power control module)or one of its sensors.
