How to Bump Start a Car
Jun 08, 2023

Knowing how to bump start a car can be a lifesaver if you find yourself in a situation where your car's battery has died and you need to get it running again. This method allows you to start a manual transmission car without the need for jumper cables or another vehicle.

What is the best way to bump start a car?

Bump starting a car involves using the momentum generated by the vehicle's motion to turn the engine and start it. Here's the step-by-step process to effectively bump start a car:

  1. Ensure safety: Park your car in a safe location away from traffic. Turn on the hazard lights and engage the parking brake.
  2. Position the car: For the best results, push starting is typically easier on a slight downward slope. If possible, choose a location with a gentle incline.
  3. Insert the key and set the ignition: Place the key in the ignition and turn it to the "on" position, but do not attempt to start the engine. Keep your foot off the clutch pedal.
  4. Engage the clutch: Depress the clutch pedal fully and keep it held down throughout the process.
  5. Gain momentum: With the clutch pedal depressed, have someone push the car from behind or release the parking brake if you're on a slope. Gradually build up some speed while maintaining the clutch position.
  6. Release the clutch: Once you've gained enough momentum (around 5-10 mph), release the clutch pedal quickly. This should transfer the engine's rotation to the transmission, starting the engine.
  7. Resume normal operation: Once the engine starts, it's crucial to resume normal driving. Rev the engine slightly and drive for a while to allow the battery to recharge.

Can you bump start a car by yourself?

While it is possible to bump start a car by yourself, it can be challenging and potentially dangerous. The process typically requires someone to push the car while you're inside, simultaneously controlling the clutch and other functions. Having an assistant is highly recommended for a safer and more effective bump start.

Can you bump start a car with a dead battery?

Yes, bump starting a car can be done with a dead battery. The process bypasses the need for electrical power from the battery by relying on the kinetic energy generated by the car's motion. However, it's important to note that bump starting won't charge the battery itself. Once the engine is running, it's advisable to drive for a while to recharge the battery or seek professional assistance if the battery is severely depleted.

Do you need to turn the key to bump start?

Yes, you need to turn the key to the "on" position while bump starting a car. This allows power to flow to the necessary electrical components, such as the ignition system and fuel pump. However, it's crucial not to turn the key to the "start" position, as this can interfere with the bump starting process.

Knowing how to bump start a car is a valuable skill that can come in handy during emergencies when your car's battery is dead. By following the step-by-step process outlined in this guide, you can successfully bump start a manual transmission vehicle. Remember to prioritise safety, seek assistance if possible, and ensure proper battery charging after the engine is running. Always consult your car's manual for specific instructions and consult a professional if you encounter persistent issues with your car's battery or starting system.
