| CHECK HARNESS BETWEEN ECM AND FUEL PUMP CONTROL UNIT. |
|
1) Disconnect the connectors from the ECM. 2) Measure the resistance of the harness between the ECM and fuel pump control unit. Connector & terminal (B135) No. 33 — (R122) No. 9: (B136) No. 12 — (B122) No. 8: |
| QUESTION | |
|
Is the resistance less than 1 Ω? | |
| Yes | No |
