What to Do If Your ATV Won't Start

Just like any other vehicle, ATVs are prone to engine trouble. However, you don't need to make a trip to a mechanic every time the engine won't start. With a few small steps, you could diagnose your ATV at home and possibly fix it yourself. Here's what you should do if your ATV won't start.

Check the Spark Plugs

If the engine turns over but won't start, you might have a faulty spark plug. Remove the spark plug, then plug it back in near a part of the engine that will ground it. Start the engine again, and watch the spark plug. If sparks come out of the plug, a faulty spark plug might have been the issue. Fortunately, replacement spark plugs are affordable and easy to find at your local hardware store.

Check the Air Filter

A dirty or broken air filter might keep your engine from starting. Check the air filter and clean it out if you haven't cleaned it in a while. You might find something obstructing the air filter, disrupting the engine's normal functions. If your air filter looks damaged or warned, you might want to buy a new air filter for your ATV.

Check the Battery

A dead battery is one of the most common problems for ATV owners. Use a multi-meter to check the voltage on your battery. If you see a reading below 12 volts, you probably need to charge the battery. Replace the battery altogether if your ATV's battery doesn't hold the charge and you find yourself regularly checking the voltage.

Check the Gas

If you haven't started your ATV in six months or more, the old gas might keep the engine from starting. Give your ATV new gas if it's been sitting in the shed for a while. You might also want to switch out the fuel filter to make sure your ATV runs smoothly all summer long.

Check the Gas Flow

A faulty fuel injector is another common issue. Take out the fuel line, then pour the gas into a container. If the gas doesn't flow freely, you might have a problem with the fuel pump or filter. The fuel line itself might also have an obstruction that prevents the normal flow of gas. You might need to clean out the fuel line or replace one of the engine parts.

You don't need years of experience to perform basic repairs on your ATV. If you're not sure how to fix the engine, you could still figure out what's going on and give your mechanic that information.
