Main Relay (Computer/Fuel System): Description and Operation

^ The Main Relay (also referred to as Fuel Injection or EGI Relay), located in the right front corner of the engine compartment near the battery, supplies power to the ECU and a number of ECU controlled devices when the ignition is switched "ON."
^ These devices include the crank angle sensor, fuel injectors and a variety of solenoid valves. The ECU completes the circuit by grounding these devices when indicated by its calculations.
