Frustrated by a car that won't start? Today, AMSOIL Dealer's Oils RGV in Mission, TX, will discuss common car starting problems and offer troubleshooting tips.
Nothing is more frustrating than hopping into your car, turning the key, and hearing... nothing. Your heart sinks as you realize you're facing the dreaded 'car won't start' scenario. But fear not, Texas drivers! Common car starting problems often have simple solutions. Let'ss dive into the most likely culprits and how to tackle them below!
Your car's battery is the heart of its electrical system. Without a healthy battery, you won't go far. Signs of a dead battery include dim headlights, slow cranking, or no response at all when you turn the key. To check your battery, first inspect the terminals for corrosion. Clean them if necessary. Next, use a voltmeter to test the battery's voltage. If it's below 12.6 volts, it's likely dead. A jump-start can get you going temporarily, but you'll need a new battery soon.
To prevent battery drain, always turn off lights and accessories when you exit your car. Regular battery checks, especially in Texas' hot climate, are essential. Extreme heat can shorten a battery's lifespan.
Even a good battery can fail to start your car if there are issues with the connections. Corrosion or loose cables can prevent electricity from flowing properly. Inspect and clean both battery terminals regularly. While you're at it, check other electrical connections for tightness and corrosion. A little maintenance can save you a lot of hassle.
Your alternator is responsible for charging the battery while the engine is running. If it's failing, your battery will gradually drain, and eventually, your car won't start. Signs of a bad alternator include dimming lights while the engine is running or warning lights on the dashboard. To check the alternator, measure the battery voltage while the engine is running. It should be around 13.5 to 14.5 volts. Also, inspect the alternator belt for wear and tightness.
The ignition system creates the spark that ignites the fuel in your engine. Problems with spark plugs, ignition coils, or the ignition switch can prevent your car from starting. Signs of ignition issues include misfires, difficulty starting, or a rough idle. Check your spark plugs for wear or fouling. Inspect the ignition coils for damage or cracks. If you suspect a problem with the ignition switch, you might need professional help.
It sounds obvious, but an empty gas tank will prevent your car from starting. If you're sure the tank isn't empty, the problem might be with the fuel pump, fuel filter, or fuel injectors. Symptoms include difficulty starting, engine sputtering, or a lack of power. Check for fuel in the tank, inspect the fuel pump and filter for damage, and if you're comfortable, test the fuel injectors.
The starter motor is responsible for cranking the engine over. If it's faulty, your car won't start. Signs of a bad starter include a clicking sound when you turn the key or slow cranking. Checking the starter solenoid is a good starting point. Testing the starter motor itself is more involved and might require professional help.
While many car problems can be diagnosed and fixed at home, some issues require the expertise of a mechanic. If you've tried the troubleshooting steps above and your car still won't start, it's time to call a professional. A mechanic can use specialized tools and knowledge to pinpoint the problem quickly and efficiently.
A car that won't start can be a real roadblock, but armed with this knowledge, you're better equipped to handle the situation. Understanding common culprits like a dead battery, fuel issues, or ignition problems can save you time and stress. Remember, a little car care goes a long way. Regular check-ups and maintenance can prevent many of these headaches and keep you cruising.
