There’s little as frustrating as turning the key in your car’s ignition and being met with silence or a mere click instead of the engine roaring to life. Such a scenario can throw off your entire day’s schedule. However, before you rush to call for roadside assistance in O’Fallon, IL, there are a few checks and fixes you can perform that might just get your car running again. Here’s a step-by-step guide on what to do when your car won’t start.
Check the Battery
The most common reason a car fails to start is a battery problem. Weak or dead batteries result in the engine not turning over, accompanied often by clicking noises. Start by examining the battery connections. Ensure that the terminals are not only clean but also tight and free from any corrosion. Corrosion can be removed using a mixture of baking soda and water, scrubbing with an old toothbrush. Additionally, measure the battery voltage with a multimeter; a reading of around 12.6 volts is ideal when the car is off. If the voltage is below 12.4 volts, the battery may need charging or replacement.
Examine the Starter Motor
If your battery is functional, the next potential culprit is the starter motor. A malfunctioning starter typically presents as a single loud click with no engine turnover. A temporary fix could be to gently tap the starter motor with a tool, which might free up a stuck gear, allowing the car to start long enough to reach a mechanic. Also, check that all connections to the starter are secure and that it is properly grounded.
Investigate the Fuel System
A car that cranks but won’t start might have an issue with its fuel system. The problem can range from a clogged fuel filter to a faulty fuel pump or injectors. Listen for a humming sound from the fuel pump when you turn the key to the “On” position; absence of this sound might indicate a pump issue. Also, ensure that there is adequate fuel in the tank, as it’s easy to overlook a simple solution like refueling.
Check the Ignition System
Another area to inspect is the ignition system, which includes spark plugs, ignition wires, or the ignition coil. Remove and inspect a spark plug for signs of damage or wear. Ensure it’s clean and properly gapped. Using an ohmmeter, you can also test the spark plug wires’ resistance; if it’s too high, consider replacing the wires.
Security System Interference
At times, a car’s security system can prevent the engine from starting, indicated by a flashing security light on the dashboard. Refer to your vehicle’s owner’s manual for instructions on how to reset the security system or try locking and unlocking the driver’s door with the key.
Check the Neutral Safety Switch
For those driving automatic vehicles, ensure the car is in either Park or Neutral. The neutral safety switch could prevent the car from starting if it’s not in the correct gear. Try starting the car in Neutral if it does not start while in Park.
When to Call for Help
If all else fails and your car still won’t start, it’s time to seek professional help in O’Fallon, IL. Contact a certified mechanic who can provide a thorough diagnosis and necessary repairs.
