This article will help you to test and troubleshoot the ignition coil, the power transistor (ignition control module) and the crankshaft position sensor on the 1990-1994 3.0L V6 Mitsubishi Montero, Mighty Max and Dodge Ram 50. No Scan Tool required for any of these tests. Whether your vehicle is suffering a No Spark No Start of Misfire Condition, you'll be able to pinpoint the problem to the ignition coil or the power transistor or the crankshaft position sensor (located within the distributor) or the spark plug wires or the distributor cap.

To make sure this test article applies to your specific Mitsubishi or Dodge vehicle, please take a look at the application chart at the bottom of this page. Ignition System Basic Working Theory Here's a little working theory of how the ignition system on your Mitsubishi 3.0L V6 ignition system creates the spark needed to get your vehicle started and running. In a nutshell, when the system is working properly and you turn the key to crank and start the engine: • The distributor shaft starts to rotate which causes the crankshaft position sensor to start generating a crankshaft and camshaft position signal, which are sent directly to the Fuel Injection Computer (Henceforth known as the PCM).

• With both of these signals (and others from other input sensors), the PCM starts to activate the power transistor (ignition control module) to start switching the ignition coil's primary current (12 Volts) ‘on and off’. • This ‘on/off’ action is also known as the Switching signal.
