Troubleshooting Engine Starting:

- Confirm the coil is receiving a strong electrical signal.

2. Check the Crankshaft Position Sensor: This sensor tells the ignition system when to fire the spark plugs. If it's faulty, it can prevent the engine from starting.

3. Fuel System Issues:

- Check fuel pressure to rule out any fuel delivery problems.

- Ensure fuel injectors are functioning and receiving the correct signals from the vehicle's computer.

4. Distributor Issues (for vehicles with distributors):

- Inspect the distributor cap and rotor for wear or damage.

- Check for proper alignment of the distributor with the engine.

5. Wiring and Connections:

- Examine all wiring connections related to the ignition system, ensuring they are secure and free of corrosion.

- Look for damaged, frayed, or loose wires that might affect the spark.

6. Fuses and Relays:

- Verify that the fuses and relays associated with the ignition system are in good condition and making proper contact.

- A blown fuse or faulty relay can interrupt the circuit responsible for starting the engine.
