1. Bad ignition coil: The ignition coil is responsible for creating the high voltage spark that ignites the air/fuel mixture in the cylinders. If the coil is faulty, it won't be able to create a spark, and the engine won't start.
2. Bad distributor cap or rotor: The distributor cap and rotor are responsible for distributing the spark from the ignition coil to the spark plugs. If either of these components is cracked, corroded, or otherwise damaged, it can prevent the spark from reaching the plugs, and the engine won't start.
3. Bad spark plug wires: The spark plug wires carry the high voltage spark from the distributor cap to the spark plugs. If any of the wires are damaged, cracked, or otherwise compromised, it can prevent the spark from reaching the plugs, and the engine won't start.
4. Bad ignition module: The ignition module is responsible for controlling the ignition coil. If the module is faulty, it won't be able to send the proper signal to the coil, and the coil won't be able to create a spark.
5. Bad crankshaft position sensor: The crankshaft position sensor tells the ignition module when to fire the spark plugs. If the sensor is faulty, the module won't know when to fire the plugs, and the engine won't start.
6. Bad camshaft position sensor: The camshaft position sensor tells the ignition module when to fire the spark plugs in relation to the camshaft. If the sensor is faulty, the module won't know when to fire the plugs, and the engine won't start.
