Can Am 570 Fuel Pump Problems

Is your Can-Am 570 sputtering, stalling, or just plain refusing to start? You're not alone. Fuel pump issues are a surprisingly common headache for owners of these popular off-road machines. A failing fuel pump can quickly turn a thrilling ride into a frustrating roadside repair, but understanding the problem and its potential solutions can save you time, money, and a lot of aggravation. Let's dive into the world of Can-Am 570 fuel pump problems and get you back on the trails.

What's the Deal with Fuel Pumps Anyway?

Before we tackle specific issues, let's quickly recap what a fuel pump does and why it's so important. Simply put, the fuel pump's job is to draw fuel from the gas tank and deliver it to the engine at the correct pressure. Without a properly functioning fuel pump, your engine won't get the fuel it needs to run, leading to a variety of performance problems. In the Can-Am 570, the fuel pump is typically located inside the fuel tank itself, making access and diagnosis a bit more involved than on some other vehicles.

Common Symptoms: Is Your Fuel Pump Giving You the Blues?

Recognizing the signs of a failing fuel pump early on can prevent a complete breakdown. Here are some of the most common symptoms to watch out for:

Hard Starting: This is often one of the first signs. The engine might crank for a long time before finally starting, or it might only start after several attempts.
Stalling: The engine might stall randomly, especially at low speeds or when idling. This is because the fuel pump isn't providing a consistent supply of fuel.
Loss of Power: You might notice a decrease in overall engine power, particularly when accelerating or climbing hills. The engine simply isn't getting enough fuel to perform optimally.
Sputtering or Hesitation: The engine might sputter, hesitate, or misfire, especially under load. This can feel like the engine is "stumbling" or "cutting out."
Rough Idle: An inconsistent or rough idle can be another indicator. The engine might struggle to maintain a steady idle speed.
Whining Noise from the Fuel Tank: A failing fuel pump can sometimes make a high-pitched whining noise coming from the fuel tank. This is often a sign that the pump is struggling to operate.
Complete Failure to Start: In the worst-case scenario, the fuel pump might fail completely, preventing the engine from starting at all.

If you're experiencing any of these symptoms, it's a good idea to investigate further and determine if the fuel pump is the culprit.

Why Do Can-Am 570 Fuel Pumps Fail?

Several factors can contribute to fuel pump failure in the Can-Am 570. Understanding these causes can help you prevent future problems.

Contaminated Fuel: This is a major culprit. Dirt, debris, and water in the fuel tank can clog the fuel filter and damage the fuel pump itself. Always use clean, fresh fuel and consider adding a fuel stabilizer, especially if your machine sits for extended periods.
Running the Tank Low: Repeatedly running the fuel tank close to empty can strain the fuel pump. The fuel acts as a coolant for the pump, and when the fuel level is low, the pump can overheat.
Age and Wear: Like any mechanical component, fuel pumps have a limited lifespan. Over time, the internal components can wear out, leading to reduced performance or complete failure.
Electrical Issues: Problems with the electrical system, such as a faulty relay or wiring, can also affect the fuel pump's operation.
Overheating: As mentioned earlier, low fuel levels can lead to overheating, but excessive engine heat in general can also contribute to fuel pump failure.

Diagnosing the Problem: Is it Really the Fuel Pump?

Before you rush out and buy a new fuel pump, it's important to confirm that it's actually the source of the problem. Here's a step-by-step approach to diagnosing fuel pump issues:

Check the Basics: Start with the simple things. Make sure you have enough fuel in the tank, and check the fuel cap to ensure it's venting properly. A clogged vent can create a vacuum in the tank, preventing fuel from flowing.
Listen for the Pump: When you turn the key to the "on" position (without starting the engine), you should hear the fuel pump prime for a few seconds. If you don't hear anything, that's a red flag.
Check the Fuel Pump Relay and Fuse: Locate the fuel pump relay and fuse in the fuse box. Consult your owner's manual for their specific locations. Test the relay and fuse to make sure they're working properly. A faulty relay or blown fuse can prevent the fuel pump from receiving power.
Fuel Pressure Test: This is the most reliable way to diagnose a fuel pump problem. You'll need a fuel pressure gauge. Connect the gauge to the fuel rail (usually located near the fuel injectors) and check the fuel pressure with the engine running. Compare the reading to the manufacturer's specifications (refer to your service manual). Low fuel pressure indicates a problem with the fuel pump.
Check the Fuel Filter: A clogged fuel filter can restrict fuel flow and mimic the symptoms of a failing fuel pump. Replace the fuel filter to see if it resolves the issue.
Inspect the Fuel Pump Wiring: Check the wiring and connectors leading to the fuel pump for any signs of damage, corrosion, or loose connections.

Important Note: Working with fuel can be dangerous. Always disconnect the battery, work in a well-ventilated area, and avoid open flames when handling fuel or fuel system components.

Fuel Pump Replacement: A DIY Project or a Trip to the Mechanic?

Replacing the fuel pump on a Can-Am 570 can be a DIY project for experienced mechanics, but it's a complex task that requires some technical knowledge and specialized tools. If you're not comfortable working on fuel systems, it's best to take your machine to a qualified mechanic.

Here's a general overview of the fuel pump replacement process:

Gather Your Tools and Supplies: You'll need a new fuel pump, a fuel pressure gauge, a socket set, a wrench set, screwdrivers, pliers, safety glasses, gloves, and a catch pan for spilled fuel.
Disconnect the Battery: This is crucial for safety.
Drain the Fuel Tank: Siphon the fuel out of the tank into a suitable container.
Remove the Fuel Tank: This usually involves disconnecting fuel lines, electrical connectors, and mounting hardware. Consult your service manual for specific instructions.
Access the Fuel Pump: The fuel pump is typically located inside the fuel tank. You'll need to remove the fuel pump assembly from the tank.
Replace the Fuel Pump: Carefully remove the old fuel pump from the assembly and install the new one. Make sure to properly connect all fuel lines and electrical connectors.
Reinstall the Fuel Pump Assembly: Place the fuel pump assembly back into the fuel tank.
Reinstall the Fuel Tank: Reconnect all fuel lines, electrical connectors, and mounting hardware.
Refill the Fuel Tank: Add fresh fuel to the tank.
Reconnect the Battery:
Test the Fuel Pump: Turn the key to the "on" position and listen for the fuel pump to prime. Check for any fuel leaks.
Start the Engine: Start the engine and check the fuel pressure with the fuel pressure gauge. Make sure the fuel pressure is within the manufacturer's specifications.

Choosing a New Fuel Pump: When selecting a replacement fuel pump, it's important to choose a high-quality unit that meets or exceeds the original equipment manufacturer (OEM) specifications. Aftermarket fuel pumps are available, but be sure to research the brand and read reviews before making a purchase. A cheap, low-quality fuel pump might fail prematurely, leaving you stranded.

Preventing Future Fuel Pump Problems: A Little Prevention Goes a Long Way

Preventing fuel pump problems is much easier (and cheaper) than dealing with a breakdown. Here are some tips to keep your fuel pump running smoothly:

Use Clean, Fresh Fuel: Always use high-quality fuel from a reputable source.
Add Fuel Stabilizer: If your machine will be sitting for an extended period, add a fuel stabilizer to prevent fuel degradation.
Avoid Running the Tank Low: Try to keep the fuel tank at least a quarter full to prevent the fuel pump from overheating.
Replace the Fuel Filter Regularly: Follow the manufacturer's recommended maintenance schedule for fuel filter replacement.
Inspect Fuel Lines and Connections: Periodically inspect the fuel lines and connections for any signs of leaks or damage.
Drain and Clean the Fuel Tank: Every few years, drain and clean the fuel tank to remove any accumulated dirt and debris.
