Main Harness [B] Secondary Fuel Injector #1 [C]
Special Tool - Measuring Adapter: 57001-1700
Secondary Fuel Injector Power Source Voltage Connections to Adapter:
For Secondary Fuel Injector #1, #2, #3, #4
Digital Meter (+) → R (injector W/R) lead
Digital Meter (–) → Battery (–) terminal
Power Source Voltage Standard: Battery Voltage for 3 seconds, and then 0 V
If the reading stays on battery voltage and never shows 0 V, check the fuel pump relay (see Relay Circuit Inspection in the Electrical System chapter).
If the fuel pump relay is normal, check the ECU for its ground and power supply (see ECU Power Supply Inspection).
If the ground and power supply are good, replace the ECU (see ECU Removal/Installation).
If there is still no battery voltage, check the fuel pump relay (see Relay Circuit Inspection in the Electrical System chapter).
If the fuel pump relay is normal, check the power source wiring (see wiring diagram in this section).
Special Tool - Hand Tester: 57001-1394
If the wiring is good, check the ECU for its ground and power supply (see ECU Power Supply Inspection).
If the ground and power supply are good, replace the ECU (see ECU Removal/Installation).
If the reading is in specification, check the output voltage (see Fuel Injector Output Voltage Inspection).
