| CHECK HARNESS BETWEEN ECM AND FUEL INJECTOR CONNECTOR. |
|
1) Disconnect the connectors from fuel injectors #3 and #4. 2) Measure the resistance of harness between ECM connector and fuel injector connector. Connector & terminal (B134) No. 20 — (E6) No. 1: (B134) No. 20 — (E17) No. 1: (B134) No. 16 — (E17) No. 2: (B134) No. 17 — (E17) No. 2: (B134) No. 18 — (E6) No. 2: (B134) No. 19 — (E6) No. 2: |
