The ignition system is designed to generate and deliver a high-voltage spark to the spark plugs at the right time, igniting the air-fuel mixture in the engine's cylinders. It works in conjunction with the engine control unit to deliver high-voltage spark to the spark plugs.
Just like other components of your vehicle, the ignition system is susceptible to various issues that can impact its performance. Common ignition system problems may arise due to wear and tear, electrical malfunctions, or other factors. The following are some of the common ignition system problems:
If you experience any symptoms of ignition system issues, get in touch with a reputable auto repair shop for an inspection.
Use a multimeter to measure the battery voltage. A fully charged battery should read around 12.6 volts. If it's below 12 volts, charge it and retest. Also, inspect the battery terminals for corrosion or loose connections. Clean terminals with a wire brush and ensure a secure connection. Sometimes, poor connections can mimic a dead battery.
Turn the ignition key and listen for a clicking sound. If you hear clicks but the engine doesn't crank, it may indicate a faulty starter solenoid.
Remove and inspect the spark plugs for fouling, wear, or deposits. Replace any damaged or excessively worn plugs. Use a spark plug tester to verify if the spark plugs are generating a spark during engine cranking.
The fuel system ensures that the engine receives the appropriate amount of fuel at the right time for combustion. Listen for a humming sound from the fuel tank when the key is turned on. If there’s no humming sound, the fuel pump may be faulty. Have an auto repair service inspect the fuel pump, fuel filter, and fuel injectors.
Use a multimeter to measure the resistance across the ignition coil's primary and secondary windings. Any deviations from the manufacturer's specifications may indicate a faulty coil. Inspect the ignition coil for visible signs of damage, such as cracks or burn marks.
Modern ignition systems comprise sophisticated components. If you’re not a qualified mechanic or someone who’s familiar with how various components of a vehicle work, troubleshooting the ignition system can be a challenge. Here at Wrights Car Care, we can help you get to the bottom of any ignition problems and get your car back on the road.
