Starter Solenoid

• The Dodge Dakota starter solenoid can fail, preventing the starter motor from engaging, which prevents the engine from starting. Test the starter solenoid's control wire with a voltmeter. If the voltmeter's readings fail to match the value outlined in your Dodge Dakota owner's manual, replace the solenoid.
  
  

Ignition Switch

• The ignition switch, which activates when your key turns to the start position, sends a charge to the starter relay, which activates the starter solenoid. Test the switch by connecting a test light to the starter solenoid terminal and turning the key to the start position. The test light should illuminate, then switch off, after you remove your key. If the test light fails to deactivate, replace the ignition switch.
  
  

Camshaft Position Sensor

• The camshaft position sensor, which relays information to the ignition module regarding which cylinder is ready to fire, can go bad due to wear or excess current. Test the sensor with an Ohmmeter. If the tested sensor value fails to meet the value specified in your owner's manual, replace the sensor.
