Test it using a multimeter to check for continuity; if it fails, replace it. Additionally, inspect the wiring harness for frayed or corroded connections, especially near the fuel tank and pump assembly. Corrosion can disrupt the electrical signal, causing intermittent pump failure. Clean corroded terminals with electrical contact cleaner and secure loose connections to restore functionality.
If the pump still isn’t operating, the issue may lie within the unit itself. A failing internal check valve or worn brushes can prevent the pump from maintaining pressure. To test this, disconnect the fuel line at the engine and crank the engine for a few seconds. If no fuel flows, the pump is likely defective. However, before replacing it, check the fuel pressure regulator, which can malfunction and cause low pressure readings. Use a fuel pressure gauge to verify the system is within the Renegade’s specified range (typically 40–60 PSI).
For those comfortable with disassembly, inspecting the pump’s internal components can save costs. Remove the pump from the fuel tank and disassemble it carefully, noting the position of each part. Look for worn brushes, damaged impellers, or debris in the housing. While rebuilding kits are available, success depends on mechanical skill and the extent of damage. If in doubt, consult a professional or opt for a replacement pump to ensure reliability.
Prevention is key to avoiding future pump issues. Regularly clean the fuel tank to prevent debris from reaching the pump, and use high-quality fuel to minimize sediment buildup. Inspect the fuel lines annually for cracks or leaks, replacing them as needed. Finally, keep the electrical system well-maintained by checking relays, fuses, and connections during routine service. Proactive care can extend the life of your Renegade 800’s fuel pump and prevent unexpected breakdowns.

Symptoms of pump failure
A failing fuel pump in your Can-Am Renegade 800 won’t announce itself with a neon sign, but it will leave clues. The first symptom often manifests as sporadic stalling, especially under acceleration or when climbing steep terrain. This happens because the pump struggles to deliver consistent fuel pressure, causing the engine to starve momentarily. If your Renegade sputters or dies unexpectedly, particularly during high-demand situations, the fuel pump should be your prime suspect.
Another telltale sign is difficulty starting the engine, even with a full tank. A weak pump may not generate enough pressure to push fuel through the system, resulting in prolonged cranking or a complete failure to start. Pay attention to whether the issue worsens after the vehicle has been sitting for a while, as residual heat can exacerbate pump inefficiency. If you find yourself repeatedly turning the key with no response, it’s time to inspect the fuel pump.
Unusual noises from the fuel tank area can also signal impending failure. A whining or buzzing sound, especially during startup or when the key is turned to the "on" position, indicates the pump’s internal components are wearing out. While some noise is normal, a sudden increase in volume or a grinding sound suggests immediate attention is needed. Ignoring these auditory warnings can lead to a complete pump failure, leaving you stranded.
Lastly, poor engine performance—such as reduced power, hesitation, or rough idling—can stem from a failing fuel pump. If your Renegade feels sluggish or unresponsive, particularly at higher RPMs, the pump may not be supplying enough fuel to meet the engine’s demands. This symptom often overlaps with other issues, like clogged injectors or a faulty sensor, but if combined with stalling or starting problems, the pump is likely the culprit.
