Luminas with a 3.1 have a Distributorless ignition system, commonly refered to as a DIS. There are three coils ( they look like large cubes with two spark plug wire fingers pointed at the radiator. They are located on the lowest side of the block btwn the bottom of the radiator and the exhaust manifold that is below 1, 3, and 5 spark plugs. Hope that helps!
