If you’re an ATV rider, you know the frustration of trying to start your vehicle, only to be met with difficulty. A common problem among ATV owners is when their vehicle is hard to start. But why is this happening? Why is your ATV hard to start?

There are a variety of reasons why is your ATV hard to start, and it’s important to understand them so that you can troubleshoot and fix the issue. In this article, we’ll explore the possible causes of hard starting ATVs and provide tips on how to diagnose and solve the problem.

Possible Causes : ATV Hard To Start

First, it’s important to make sure that you’re using fresh gasoline. Old gasoline can cause starting issues, so if you’ve been using the same gas for a while, it might be time to get a new can.

Another possibility is that your spark plugs are dirty or damaged. This can prevent the spark from igniting the gasoline, and cause starting difficulties. Try cleaning or replacing your spark plugs to see if that solves the problem.

Finally, it’s possible that there is an issue with your ATV’s carburetor. If you think this might be the case, it’s best to take it to a mechanic or dealership for service. If you’re having trouble starting your ATV, try these potential solutions and see if they help get your vehicle up and running again.

ATV Hard to start: How to fix?

Check the Battery

If your ATV is having difficulty starting, one of the first things you should check is the battery. A weak or dead battery is a common cause of starting problems.

If your battery is more than three years old, it’s probably time to replace it. Even if it’s not that old, batteries can lose their charge for a variety of reasons, including extended periods of inactivity, cold weather, or faulty connections.

To check your battery’s charge, use a voltmeter or multimeter to test the voltage at the battery terminals. If the reading is 12.6 volts or less, your battery needs to be recharged. You can do this by hooking up a charger to the terminals or by jump-starting the ATV from another vehicle.

Once you’ve recharged the battery, clean the terminals and connectors with a wire brush to ensure good contact. Tighten any loose connections and make sure that the terminal clamps are secure.

Check the Oil

If your ATV is hard to start, the first thing you should check is the oil level. If the oil level is low, it can cause all sorts of problems, including making it hard to start.

To check the oil level, remove the dipstick from the oil tank and wipe it clean with a rag. Then reinsert the dipstick and pull it out again. The oil level should be between the two marks on the dipstick. If it’s not, add more oil until it reaches the correct level.

Check the Spark Plugs

If your ATV is hard to start, one of the first things you should check is the spark plugs. Over time, spark plugs can become fouled with oil and debris, which can prevent them from sparking properly.

If your spark plugs are dirty or damaged, it can be difficult for your ATV to start. You should check your spark plugs periodically to make sure they are clean and in good condition. Replacing dirty or damaged spark plugs can help improve starting performance.

Check the Fuel System

If your ATV is hard to start, the first thing you should check is the fuel system. Make sure there is fresh gas in the tank and that the fuel line is not clogged. If the fuel filter is dirty, it may need to be replaced. Also, check the spark plug to see if it needs to be cleaned or replaced.

Check for Loose Wires

If your ATV is hard to start, one potential issue could be loose wires. Over time, vibrations from riding can cause wires to loosen and come detached. Visually inspect all of the wire connections on your ATV, including the battery terminals, spark plug wires, and ignition coil wires. If any of the connections are loose, tighten them up and see if that solves the problem.


There are a few reasons why your ATV might be hard to start. It could be due to a problem with the spark plugs, the fuel mixture, or the carburetor. If you’re not sure what the problem is, it’s best to take it to a mechanic and have them take a look.

In the meantime, make sure you’re using fresh gas and that all of the connections are tight so that air can’t get in and disrupt the fuel mixture.
