Main Relay (Computer/Fuel System): Testing and Inspection
Control Relay
System Schematic
Failure of the control relay could interrupt power supply to the fuel pump, injectors and ECU, resulting in start failure. Also see Fuel Pump and/or
Power Circuits in TESTING PROCEDURES.

Caution
Use caution when connecting jumper wires to the relay. If they are incorrectly connected the relay will be damaged.
Test control relay by checking continuity between the following terminals of the control relay coil.
Confirm circuit tester polarity before checking continuity.
