1994 Olds Achieva mileage: 85,000. My car isn't firing on cylinders one and three. I have tested the injector electrical connectors with a neon light and they all flashed. I swapped number one injector with number two and number one cylinder still didn't fire so I don't think it is the injector system. I have changed the spark plugs and the fuel filter also. I have taken the ignition coils and swapped them and the same two cylinders are not working. This engine has the integrated direct ignition so I am not too familiar with the ignition system. I’m trying to avoid the cost of taking it to a dealer. Any suggestions would be greatly appreciated.
