I dont know the location of the ignition module. The computer tells the ignition module to fire the ignition coil and the coil sends spark to the distributor where the rotor inside ditributor sends the spark to the path of least resistance . This is usually the cyilinder that is to be fired unless there is something wrong with the cap or rotor. If you know the ignition module and ignition coil are good you may have a bad ignition switch. I have never hears of an ignition ignitor whatever that is.
