Fuel Injector Test
NOTE: The harness connector and locking spring is
bonded to the fuel injectors with an epoxy. DO NOT
attempt to disconnect the connector from the fuel
injectors. Damage will occur to the injector and/or
harness if attempting to separate at that location.
Separate the fuel injector from the vehicle harness
as shown in the illustration below.
IMPORTANT: Take note of PTO and MAG fuel
injector harness connectors before disconnecting
them. The harnesses are different and can not be
connected incorrectly (PTO - Gray; MAG - Black).
The fuel injectors are non-serviceable. If diagnosis
indicates a problem with either injector, test the
resistance of the fuel injector (s) by measuring between
the two harness pin terminals:
Fuel Injector Resistance Specification:
11.4 Ω - 12.6 Ω
NOTE: Be sure to connect like colored fuel injector
connectors for proper engine function (PTO = GRAY,
MAG = BLACK).
Fuel Injector Replacement
1. Be sure the engine has cooled enough to work on.
2. Remove seats and rear service panel (see chapter
5):
• RZR / RZR S: Remove both driver and passenger
seats
• RZR 4: Remove both rear passenger seats
3. Remove the rear cargo box (see chapter 5).
4. Place a suitable container below the quick connect
plug at the end of the fuel rail. Hold a shop rag over
the plug and remove it to depressurize the fuel
system.
