Lawn Mower Won’t Start? Troubleshooting Tips to Get Your Engine Running Again”

1. Check the Fuel System

The fuel system is often a culprit when a lawn mower won’t start. Here’s what you can do:

  1. Check the Fuel Level: Ensure that there is enough fuel in the tank to power the engine. If it’s low, refill it with fresh, clean gasoline.
  2. Check the Fuel Filter: A clogged fuel filter can prevent fuel flow and inhibit engine starting. If dirty or clogged, replace the fuel filter according to the manufacturer’s instructions.

2. Inspect the Ignition System

A faulty ignition system can also be the cause of a non-starting lawn mower. Consider the following:

  1. Check the Spark Plug: Remove the spark plug and inspect it for fouling, damage, or wear. Clean or replace the spark plug as necessary.
  2. Check the Ignition Coil: Ensure that the ignition coil is securely connected and functioning correctly. A faulty ignition coil may require replacement.

3. Examine the Air Filter

A dirty or clogged air filter can impede air intake and affect engine performance. Take the following steps:

  1. Remove the Air Filter: Locate the air filter housing and remove the air filter. Inspect it for dirt, debris, or damage.
  2. Clean or Replace the Air Filter: If the air filter is dirty, clean it according to the manufacturer’s instructions. If it’s damaged or excessively dirty, replace it with a new one.

4. Assess the Engine Oil

Low or dirty engine oil can lead to engine problems. Consider the following:

  1. Check the Oil Level: Ensure that the engine oil level is sufficient. If it’s low, top it up with the recommended oil.
  2. Change the Oil: If the oil appears dirty or hasn’t been changed in a while, consider replacing it following the manufacturer’s guidelines.

5. Review the Safety Features

Modern lawn mowers are equipped with various safety features that may prevent the engine from starting. Make sure to:

  1. Check the Safety Features: Ensure that the blade control lever is disengaged, the parking brake is engaged (if applicable), and the operator presence control (OPC) lever is properly engaged.

6. Seek Professional Help

If you’ve exhausted the troubleshooting steps and your lawn mower still won’t start, it may be time to seek professional assistance. A qualified technician can diagnose and repair any underlying issues that may require specialized knowledge or tools.


Dealing with a lawn mower that won’t start can be frustrating, but with a systematic approach, you can troubleshoot and identify the problem. Start by checking the fuel system, inspecting the ignition system, examining the air filter, assessing the engine oil, and reviewing the safety features.
