isuzu elf n series ECM wiring diagram please
 

im working on an NKR66E with the 4HF1-1 engine. It just wouldnt start after it was parked for a few hours. It cranks normally but doesnt run. Checked and found no fuel getting to the injectors from the pump. I tried to retrieve the OBD flash codes but no codes at all,actually, no flashes even. checked the ECM connectors and found no constant 24 volt supply, only switched voltage. I may be wrong but i believe there should be an unswitched supply too. All the fuses ceck out fine. It has the ECM under the radio and has 4 multi plug connectors. I cant source the right schematic online. The available one shows a 2 plug ECM. Can anyone help me please?
