Fuel Injector Test
NOTE: The Bosch harness connector and locking
spring is bonded to the fuel injectors with an epoxy
mix. DO NOT attempt to disconnect the Bosch
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 by disconnecting at the end of the
harness as shown in this procedure.
The fuel injectors are non-serviceable. If fault code 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 Replacement
1. Be sure the engine has cooled enough to work on.
2. Depressurize the fuel system by connecting the Fuel
Pressure Gauge Kit PU-43506-A to the test valve at the end
of the fuel rail and properly drain the fuel into a suitable
container.
3. Remove the exhaust pipe between the exhaust silencer and
the elbow pipe to allow better access to the fuel injector rail.
4. Remove the engine breather hose from the valve cover.
5. Remove both driver and passenger seats and remove the
rear service panel.
