1. There is no voltage between ECU terminal No. 10, No. 20 and/or No. 30 and E01 and/or E02. (IG SW ON)
2. Check that there is voltage between ECU terminal No. 10, No. 20 or No. 30 and body ground.
NO → OK
Check wiring between ECU terminal E01 and/or E02 and body ground.
OK → BAD
Try another ECU. → Repair or replace.
Check fusible links and ignition switch. → BAD → Repair or replace.
OK ↓
3. Check resistance of each injector.
STD resistance: Approx. 13.8 Ω
OK → BAD
Replace injector.
Check wiring between ECU terminal No. 10, No. 20 and/or No. 30 and battery. → BAD → Repair or replace.
