Dodge Durango no start condition likely related to bad PCM issue resolved by replacing voltage regulator and PCM on Dodge Durango

Some Dodge Durango owners report experiencing a no-start condition, often attributed to a dead battery, which is the most common cause. Other potential culprits include the starter, alternator, ignition system, fuel system, or the vehicle's computer. Owners have noted that a bad starter or alternator can also lead to starting issues. It is crucial for owners to accurately diagnose the problem, as checking for trouble codes with an OBDII scanner can provide valuable insights when the engine cranks but fails to start. Some have experienced slow cranking or no cranking at all, pointing to a weak or dead battery as a likely issue. Additionally, a clicking noise during attempts to start may indicate a weak battery. In cases where the Powertrain Control Module (PCM) is suspected, replacing the voltage regulator and PCM may resolve the starting problems. Therefore, methodically checking these components is essential for identifying the root cause of the no-start condition in a Dodge Durango.
