OEM Yamaha Snowmobile Solid State Fuel Pump Relay (Red Relay) On 2006 to 2013 fuel injected models (Apex, FX Nytro, Vector, Phazer, RS Venture GT) the mechanical fuel pump relay can freeze in extreme cold temperatures while the unit is shut off for an extended period. When this occurs, the engine will crank but not start due to lack of fuel pressure. To cure this install this new updated solid state fuel pump relay.
