- Check Battery Voltage: Use a multimeter to ensure the battery voltage is around 12.6 volts.
- Clean Terminals: Remove any corrosion from battery terminals and ensure they are tightly connected.
Step 2: Examine the Ignition Switch
A faulty ignition switch can prevent your car from starting.

- Remove Spark Plugs: Look for signs of wear or damage.
- Test Spark Plug Wires: Check for cracks or frayed wires that may disrupt the ignition process.
Step 4: Check the Ignition Coil
The ignition coil is essential for converting the battery's low voltage to the high voltage needed for the spark plugs.
- Measure Coil Resistance: Use an ohmmeter to check if the coil’s resistance matches manufacturer specifications.
- Inspect for Damage: Look for cracks or other physical damage.
Step 5: Evaluate the Distributor Cap and Rotor
In older vehicles, the distributor cap and rotor distribute the electrical current to the spark plugs.
- Inspect Cap and Rotor: Look for cracks, carbon tracks, and worn contacts.
- Replace if Necessary: Damaged components should be replaced to ensure proper function.
Step 6: Check for Faulty Sensors
Modern vehicles rely on various sensors to control the ignition system.
- Scan for Error Codes: Use an OBD-II scanner to identify faulty sensors.

Step 7: Verify Fuel Supply
Sometimes, ignition problems are actually fuel supply issues.
