How to Fix an Ariens EFI Snowblower That Won’t Start | Troubleshooting Tips

You may need to check the fuel, spark plug and battery connections, as well as the carburetor, to diagnose the issue why your Ariens EFI snowblower won’t start.

Ariens Efi Snowblower Won’T Start

The Ariens EFI Snowblower is an efficient and powerful machine designed for easy winter maintenance. Unfortunately, users may sometimes encounter an issue in which the EFI Snowblower won’t start. This can be a source of frustration, but there are a few common causes that can usually be resolved relatively quickly. It’s important to understand the underlying cause of the issue in order to successfully solve the problem. This document provides an overview of the some of the possible causes and steps for troubleshooting the snowblower so it will start.

Checking the Gasoline

When an Ariens EFI snowblower won’t start, the first thing to check is the gasoline. Make sure that you are using a fresh and clean gasoline without any water or other contaminants. The gasoline should be between 87 octane and 94 octane to ensure optimal performance of the snowblower. If you are using a fuel stabilizer, add it to your tank according to the manufacturer’s instructions. Additionally, ensure that the fuel cap is tightened sufficiently so that no air can enter the tank while it is running.

Inspecting the Spark Plug

The spark plug is essential for starting and running your Ariens EFI snowblower. Inspect the spark plug for signs of damage such as cracking or corrosion. If there is any sign of damage, replace it with a new one and make sure that it is correctly gapped according to the manufacturer’s specifications. Additionally, make sure that all of the connections between the spark plug and ignition system are properly secured and tight. Finally, if you have an adjustable gap spark plug, make sure that it has been adjusted correctly for optimal performance.

Checking for Fuel Delivery

If you have checked both the gasoline and spark plug but your Ariens EFI snowblower still won’t start, then you may have a fuel delivery problem. Start by checking all of the fuel lines from the tank to engine for clogs or blockages due to dirt or debris. If there is no blockage, then check for faulty seals on both ends of each line which could be causing fuel leakage and preventing it from reaching its destination in sufficient amounts. If everything looks fine with these components then move on to checking other parts such as the carburetor and fuel pump which could also be causing problems with fuel delivery.

Testing Electrical Components

If all of these components appear to be in working order but your Ariens EFI snowblower still won’t start, then you may need to test some electrical components such as wires, fuses, relays, switches etc. Start by checking each component one at a time with a multimeter or test light until you find out what component is faulty or not functioning correctly thus preventing your engine from starting up properly. Once you have identified this component replace it with an identical part from your local store or online retailer if necessary before attempting to start your snowblower again..

Fuel Issues

The Ariens Efi Snowblower is designed to run on unleaded gasoline with an octane rating of 87 or higher. If the fuel in the tank does not meet these requirements, the snowblower may not start. To check if there are fuel issues, first make sure that the tank is full of fresh gasoline. If it is not, fill it with fresh gasoline and try to start the snowblower again. If this doesn’t solve the problem, then you should check the fuel filter. The fuel filter prevents dirt and debris from entering into the engine and can become clogged over time. Replace or clean the filter if necessary and try to start the snowblower again.

Spark Plug

If replacing or cleaning the fuel filter doesn’t solve your problem, then you should check the spark plug. The spark plug is responsible for igniting the fuel in order for it to combust and power your Ariens Efi Snowblower. If it is dirty or worn, then it won’t be able to ignite properly and your snowblower will not start. To check if this is your issue, remove the spark plug and inspect it for signs of wear or damage. If it looks OK, then clean it with a wire brush before reinstalling it into the engine.

Fuel Lines

If all else fails, you should check your Ariens Efi Snowblower’s fuel lines for blockages or leaks. These lines deliver gasoline from the tank to the engine and can become blocked by dirt or debris over time. Inspect these lines for any signs of blockage or damage and replace them if necessary before trying to start your snowblower again.


The last thing you should check if your Ariens Efi Snowblower won’t start is its carburetor. This component mixes air with gasoline in order for proper combustion to occur during engine operation. If this mixture isn’t correct then your Ariens Efi Snowblower won’t be able to start up properly. You can inspect this component yourself but be aware that some components in a carburetor may need special tools to adjust properly so you may need to take your snowblower into a professional mechanic if needed.

FAQ & Answers

Q: Why won’t my Ariens EFI snowblower start?
A: If your Ariens EFI snowblower won’t start, the cause may be a lack of fuel, a dirty carburetor, or a faulty spark plug. Check each of these components to determine the cause.

Q: How do I check the spark plug?
A: You can check the spark plug by removing it from the engine and inspecting it for any signs of damage or wear. If the spark plug looks worn or damaged, replace it with a new one.

Q: How do I clean a carburetor on an Ariens EFI snowblower?
