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.
