Fuel Pump Assembly
The internal electric motor in the pump assembly is prone to seizure or winding failure, which prevents the system from reaching the required 51 PSI for the fuel injectors. Without sufficient pressure, the injectors cannot atomize the fuel, resulting in a 'dry' combustion chamber despite the engine cranking. This is the most common mechanical failure point for the Rotax 850 EFI system.

Fuel Pump Relay
Oxidation on the internal contact points of the relay creates high electrical resistance, preventing sufficient current from reaching the fuel pump motor. Even if the relay is audible, the voltage drop across the pitted contacts results in a pump that cannot spin at the necessary RPM to prime the fuel rail. This is a common environmental failure due to the fuse box location on ATVs.

NGK Spark Plugs (DCPR8E)
The high-compression Rotax V-twin is sensitive to spark plug gap and carbon fouling. If the engine is started and stopped quickly without reaching operating temperature, raw fuel can soak the ceramic insulator, creating a path of least resistance that prevents the spark from jumping the gap during subsequent start attempts.
