Let's face it, there's nothing more frustrating than turning the key (or pressing the button) on your Can-Am ATV or side-by-side, only to be met with silence, clicking, or a sluggish attempt to start. These machines are built for adventure, but a starting problem can quickly turn an exciting day into a major headache. We're going to dive into the common culprits behind Can-Am starting issues and arm you with the knowledge to diagnose and (hopefully) fix the problem yourself.
Why a Reliable Start Matters More Than You Think
Beyond the obvious inconvenience, a consistent starting problem can indicate deeper underlying issues within your Can-Am. Ignoring the symptoms can lead to more expensive repairs down the road. Think of it as your machine giving you a warning sign – listen to it! A reliable start also ensures your safety, especially when you're out on the trails, far from help.
The Usual Suspects: Battery Blues
Let's start with the most common offender: the battery. A weak or dead battery is the number one reason why Can-Ams refuse to start.
-
The Obvious: Check the Connections: First things first, inspect the battery terminals. Are they clean and securely connected? Corrosion can build up over time, creating resistance and preventing the flow of electricity. Use a wire brush or battery terminal cleaner to remove any corrosion. Make sure the connections are tight; a loose connection can also cause intermittent starting problems.
-
Voltage is Key: Grab a voltmeter and check the battery voltage. A healthy battery should read around 12.6 volts when the engine is off. If it's significantly lower (below 12 volts), your battery is likely discharged.
-
Load Test Time: Even if the battery shows a good voltage reading, it might not be able to deliver enough current to start the engine. This is where a load test comes in. A load test simulates the draw of the starter motor and reveals whether the battery can hold its voltage under load. Many auto parts stores offer free battery testing services. If the battery fails the load test, it's time for a replacement.
-
Battery Age Matters: Batteries don't last forever. Even with proper maintenance, they have a limited lifespan. Typically, an ATV or side-by-side battery will last between 3 and 5 years. If your battery is nearing the end of its expected lifespan, it might be time to consider a replacement, even if it seems to be holding a charge.
Pro Tip: If you're storing your Can-Am for an extended period (like during the off-season), use a battery tender or maintainer to keep the battery charged. This will significantly extend its lifespan.
Starter Issues: The Engine's Muscle
If the battery checks out, the next place to investigate is the starter motor itself. The starter is responsible for cranking the engine until it starts, and if it's failing, you'll experience starting problems.
-
The Dreaded Click: A single click when you try to start the engine often indicates a problem with the starter solenoid. The solenoid is a relay that sends power to the starter motor. If it's faulty, it won't deliver the necessary current. You can test the solenoid by jumping the two large terminals with a screwdriver (be careful!). If the starter engages, the solenoid is likely the culprit.
-
Slow Cranking: If the starter motor cranks the engine slowly, it could be a sign of a worn-out starter motor or a weak battery. If the battery is good, the starter motor itself might be the problem.
-
Starter Motor Replacement: Replacing a starter motor is usually a straightforward process. However, it's essential to use the correct replacement part for your specific Can-Am model. Consult your owner's manual or a reputable parts dealer to ensure you get the right starter motor.
-
Check the Wiring: Inspect the wiring to the starter motor for any signs of damage or corrosion. A loose or corroded connection can prevent the starter from receiving enough power.
Fuel Delivery Problems: Starving the Engine
A healthy engine needs fuel to run. If your Can-Am isn't getting enough fuel, it won't start.
-
Empty Tank? Obvious, But Check!: It sounds silly, but make sure you have enough fuel in the tank! A low fuel level can cause starting problems, especially on inclines.
-
Fuel Filter Clogged: The fuel filter prevents debris from entering the fuel system. Over time, it can become clogged, restricting fuel flow. Replacing the fuel filter is a relatively simple and inexpensive maintenance task that can resolve many starting problems.
-
Fuel Pump Issues: The fuel pump is responsible for delivering fuel from the tank to the engine. If the fuel pump is failing, it won't provide enough fuel pressure, leading to starting problems. You can test the fuel pump pressure using a fuel pressure gauge.
-
Injector Problems (EFI Models): If your Can-Am has electronic fuel injection (EFI), the fuel injectors could be clogged or faulty. Clogged injectors can prevent fuel from being sprayed into the engine. Fuel injector cleaner can sometimes resolve minor clogs, but severely clogged injectors might need to be professionally cleaned or replaced.
-
Ventilation Issues: Confirm the gas tank vent is not plugged. This will prevent fuel from flowing freely.
Ignition System Woes: Sparking Trouble
The ignition system is responsible for igniting the air-fuel mixture in the engine. If there's a problem with the ignition system, the engine won't start.
-
Spark Plug Check: Start by checking the spark plug. Remove the spark plug and inspect it for signs of wear, fouling, or damage. A fouled spark plug can prevent the engine from starting. Clean the spark plug or replace it if necessary.
-
Spark Test: To test if the spark plug is firing, reconnect it to the spark plug wire, ground the plug against the engine block, and crank the engine. You should see a strong, consistent spark. If there's no spark, or the spark is weak, there's a problem with the ignition system.
-
Ignition Coil Problems: The ignition coil amplifies the voltage from the battery to create the spark. If the ignition coil is failing, it won't deliver enough voltage to the spark plug.
-
Crankshaft Position Sensor (CPS): The CPS tells the engine control unit (ECU) the position of the crankshaft. If the CPS is faulty, the ECU won't know when to fire the spark plug.
Safety Switches: Overlooked Protectors
Can-Am ATVs and side-by-sides are equipped with safety switches to prevent accidental starting. These switches can sometimes cause starting problems if they're faulty or not properly engaged.
-
Neutral/Park Switch: Make sure the transmission is in neutral or park. A faulty neutral/park switch can prevent the engine from starting.
-
Brake Switch: Some models require you to apply the brakes before starting the engine. A faulty brake switch can prevent the engine from starting.
Other Potential Culprits
While the above are the most common causes, here are a few other possibilities to consider:
-
Flooded Engine: If you've been cranking the engine for a while without success, it might be flooded with fuel. To clear a flooded engine, hold the throttle wide open while cranking the engine.
-
Compression Issues: Low compression can make it difficult for the engine to start. Compression issues can be caused by worn piston rings, leaky valves, or a blown head gasket.
-
ECU Problems: In rare cases, the engine control unit (ECU) can be the cause of starting problems. The ECU controls various engine functions, including fuel injection and ignition timing.
