Fuel Injectors
The fuel injectors are solenoids that allow pressurized fuel
into the intake tract. The injectors are timed to the engine
cycle and triggered sequentially. The power for the injectors
comes from the system relay. The system relay also provides
power for the fuel pump and the ignition coil. The ECM pro-
vides the path to ground to trigger the injectors.
NOTE
ECM fuse and system relay failures or wiring harness prob-
lems will cause 12 volt power to be lost to both injectors, igni-
