What to Do When Your Car Won’t Start

April 2, 2024

Nothing is more annoying than turning on the key and getting either a succession of menacing clicks or complete silence. Drivers who are daring need not worry; we have you covered. We’ll take you through the most frequent causes of your car’s refusal to dance to the ignition song in this tutorial, giving you the tools you need to troubleshoot like an expert. Now fasten your seatbelt and let’s start the engine up again!

1. Silent Treatment – No Clicks, No Sounds

Possible Causes:

  • Dead Battery: The most common culprit. Over time, batteries wear out, especially if you keep the lights on or have other electronic devices running while the engine is turned off. 
  • Loose or Corroded Battery Connections: If the battery connections are loose or corroded, it can prevent the electrical current from reaching the starter motor, resulting in a silent response when you turn the key. 

What to Do:

  1. Check Lights and Electronics: Are your headlights dim? This could be a sign of a weak battery. If so, try turning off all unnecessary electronics and see if that improves the battery’s performance. If the car won’t start even after you do this, it may be time to replace the battery. 
  2. Jumpstart: If you have jumper cables and a willing friend, jumpstarting your car might do the trick. Jumpstarting your car involves connecting the positive and negative terminals of your battery to the corresponding terminals of another vehicle’s battery. This can provide enough power to start your car and recharge your battery. However, if jumpstarting doesn’t work, it may indicate a more serious issue with your car’s electrical system or starter motor. In that case, it’s best to consult a professional mechanic for further assistance. 

Pro Tip: Consider purchasing a portable jump starter. They’re a lifesaver in sticky circumstances. 

2. Click, Click, Click – The Infamous Clicking Sound

Possible Causes:

  • Starter Problems: When you turn the key, the starter motor turns the engine. Clicking sounds without the engine turning over might signal a problem with the starter. This could be due to a weak or dead battery, which is unable to provide enough power to the starter motor. 
  • Faulty Solenoid: Another possible cause could be a faulty solenoid, which is responsible for engaging the starter motor. It’s important to have these issues diagnosed and repaired by a professional mechanic to ensure the proper functioning of your car’s electrical system. 

What to Do:

  1. Check the Battery Connections: Loose or corroded connections might cause problems with the starter. When your car won’t start, check if the battery terminals are clean and tight. If the battery connections are loose or corroded, it can prevent the proper flow of electricity to the starter motor. In some cases, simply tightening or cleaning the battery terminals can resolve the issue and restore the proper functioning of the starter motor. However, if the problem persists, it is recommended to seek assistance from a professional mechanic to diagnose and repair any underlying issues with the electrical system. 
  2. Give the Starter a Love Tap: Seriously, a gentle tap with a wrench or hammer might engage a reluctant starter. This method can sometimes work when your car won’t start because it can help free up any stuck or jammed components within the starter motor. However, it is important to note that this is only a temporary solution and should not be relied upon as a long-term fix. If the starter continues to have issues, it is best to have it inspected and repaired by a professional mechanic to avoid further damage or potential safety hazards. 

Pro Tip: If the tapping works, it’s time to replace the starter. Continuing to rely on tapping as a solution may cause further damage to the starter motor and could potentially lead to more expensive repairs down the line. It is recommended to consult with a professional mechanic for a proper diagnosis and replacement of the starter to ensure optimal performance and safety. 

3. Engine Cranks but Doesn’t Start – The Silent Humming

Possible Causes:

  • Fuel Issues: Your car needs fuel to go places. If there’s a problem with the fuel system, your engine might crank but not start. This could be due to a variety of issues such as a clogged fuel filter, a faulty fuel pump, or a problem with the fuel injectors. It is important to have the fuel system inspected and repaired by a qualified mechanic to resolve the issue and get your car running smoothly again. 

What to Do:

  1. Check the Fuel Gauge: Ensure you have enough fuel in the tank. Running out of fuel is a common cause of a car not starting. If the fuel gauge shows that you have a low fuel level, it is recommended to refuel your car before troubleshooting any other potential issues. 
  2. Listen for the Fuel Pump: When you turn the key to the “on” position (not start), you should hear a humming sound from the fuel pump. No sound could mean a faulty pump. If you do not hear any sound from the fuel pump, it is advisable to have it checked by a professional mechanic. A faulty fuel pump can prevent the proper delivery of fuel to the engine, causing starting issues. 

Pro Tip: Carry a small can of starter fluid with you. If your car starts with a quick spray, it might be a fuel delivery issue.

4. Whining or Grinding Noise – Unpleasant Serenades

Possible Causes:

  • Problems with the Starter or Flywheel: Relentless whirring or grinding sounds when the key is turned may indicate that there are issues with the starter or the flywheel that it engages. These components may be worn out or damaged, preventing the starter from properly engaging with the flywheel. It is important to have these issues addressed promptly to avoid further damage to the engine. 

What to Do:

  1. Engage Neutral: If your car has an automatic transmission, try starting it in neutral. Sometimes, the park position might not align perfectly, causing the starter to misbehave. 
  2. Look for Loose Connections: The noise may be coming from a damaged flywheel or loose starter bolts. If you notice any loose connections, such as loose bolts or a damaged flywheel, it is crucial to have them tightened or replaced by a professional mechanic. 

Pro Tip: If the noise persists, it’s time for a visit to the mechanic. Ignoring these issues can lead to more severe damage to the starter or other engine components. 

5. Lights Flicker, Engine Won’t Start – The Mysterious Twilight Zone

Possible Causes:

  • Electrical Gremlins: A variety of electrical problems may result in a show of flickering lights but an engine that refuses to start. These issues could be caused by a faulty alternator, a weak battery, or loose electrical connections. 

What to Do:

  1. Inspect Fuses: A blown fuse could be the culprit. Check your car’s manual to locate the fuse box and inspect the relevant fuses. If any fuses are blown, replace them with new ones of the same rating. 
  2. Battery Voltage: Use a multimeter to check the voltage of your battery. A low reading might point to a charging system issue. If the battery voltage is low, it may indicate that the alternator is not charging the battery properly. In this case, it is recommended to have the alternator tested and possibly replaced by a professional mechanic. 

Pro Tip: If you’re not comfortable with electrical systems, seek professional help.

6. It Starts, Then Dies – The Frustrating Staller

Possible Causes:

  • Idle Issues: Your car might start but then stall due to problems with the idle control system.

What to Do:

  1. Clean the Throttle Body: A dirty throttle body can disrupt the air-fuel mixture. Use throttle body cleaner to give it a good scrub.
  2. Check for Vacuum Leaks: Cracked or disconnected vacuum hoses might be the culprits.

Pro Tip: If the problem persists, a trip to the mechanic might be necessary.

7. Ignition Switch Woes – The Silent Saboteur

Possible Causes:

  • Faulty Ignition Switch: The ignition switch is responsible for sending power to the starter. If it’s on strike, your car won’t start.

What to Do:

  1. Check Other Electrical Components: If your radio and lights work, it’s probably not the ignition switch.
  2. Try the Spare Key: A worn-out key might cause ignition switch issues. If you have a spare, give it a shot.

Pro Tip: Ignition switch issues can be tricky. If in doubt, consult with a professional.

8. Noises from the Engine Bay – The Mechanical Symphony

Possible Causes:

  • Engine Seized: In extreme cases, an engine can seize due to lack of oil or internal damage.

What to Do:

  1. Check Oil Level: Ensure there’s enough oil in your engine. Low oil levels can lead to engine damage.
  2. Attempt to Turn the Crankshaft: If the engine is seized, attempting to turn the crankshaft with a wrench might free it up.

Pro Tip: Engine seizures are serious. If you suspect this issue, seek professional assistance.
