Fuel Pump Assembly
The Pro XP's electronic fuel injection requires precise fuel pressure (typically 58 PSI) to fire the injectors. Over time, the internal pump motor or pressure regulator can degrade, allowing the engine to crank normally while failing to provide enough pressure to create a combustible aerosol in the cylinders. Replacing the entire assembly ensures both the pump and the integrated regulator are within factory specifications.

NGK Iridium Spark Plugs
Polaris engines are prone to 'fuel fouling' of the spark plugs if the vehicle is started and stopped frequently in cold weather without reaching full operating temperature. Carbon deposits on the ceramic insulator create an alternative path for the electrical arc, preventing a spark from jumping the gap during high-compression cranking. Installing fresh plugs restores the necessary ignition energy for combustion.

Fuel Injector Harness Repair Kit
The Pro XP engine produces significant harmonic vibrations that can lead to work-hardening and eventual internal breakage of the copper strands within the fuel injector pigtail connectors. While the connector may appear physically attached, the lack of electrical continuity prevents the ECU from pulsing the injectors during the start sequence. This kit replaces the vulnerable wiring with reinforced leads.
