A 'spark ignition ' engine is your regular gasoline engine as opposed to a diesel, which is a 'compression ignition' engine
The 1990 Chevy Celebrity engine is distributorless, the ignition is handled by a combination of the engine control module(computer) and the ignition control module. You did not mention which engine the car has. If your car has the 4 cylinder engine the ignition control module is below the intake manifold at the rear of the engine.
