A Chrysler owner can easily troubleshoot his vehicle by checking the ignition system, the fuel system and the mechanical system. Vehicles need air, fuel and spark to start, and those three systems provide those elements.

The owner must first determine if his vehicle does not crank, or if it does not start. A vehicle that does not crank does nothing when the driver turns the key in the ignition. A vehicle does not start if the engine cranks but never catches. Vehicles that do not crank may have a failed starter motor, a failed neutral safety switch, a failed ignition switch, or a locked-up engine. The owner needs a fuel pressure gauge, spark tester, compression gauge and multimeter to test his vehicle's systems.

The ignition system provides the spark, and the vehicle does not have the spark if it cannot get power to the ignition coil pack, it has a bad ignition coil pack, or the crankshaft position sensor fails. The owner can methodically test each component of the ignition system to find the failure.

The fuel system provides the engine with fuel. The engine does not receive fuel if the vehicle has a bad fuel pump relay, a bad automatic shutdown relay or a failed fuel pump. The owner can test the fuel pump independently to be sure it fires.

The engine receives air through its pistons and cylinder head valves. Internal engine problems can cause the engine to crank but not start, including a blown head gasket, a blown engine or a broken timing belt.
