GENERAL
Front and Rear Fuel Injectors
See
. The fuel injectors are solenoids that allow
pressurized fuel into the engine intake tract. The fuel injectors
are timed to the engine cycle and are triggered sequentially.
NOTE
Front and rear fuel injectors are not interchangeable due to
specific spray patterns designed for the engine.
The power for the fuel injectors comes from the ignition relay.
The ignition relay also provides power for fuel pump, Electronic
Control Module (ECM) and the ignition coil. The ECM provides
the path to ground to trigger the fuel injectors.
NOTE
Ignition relay failure or wiring harness problems will cause 12
volt power to be lost to both fuel injectors, ignition coil, ECM
and fuel pump.
