Ignition module is earthed to body.
I followed this --
Switch ignition ON and probe each terminal of an injector wiring connector with a test lamp to earth.
If test lamp lights when the probe contacts the light blue wire terminal,check the wiring harness for shorts to voltage between the
injector wiring connectors and the control unit wiring connector terminals D15 and D16.
If the test lamp does not light when the probe contacts the red wire terminal,a fault in the EFI relay or circuit is indicated.
If test lamp lights when the probe contacts the red wire terminal,proceed as follows...
Switch ignition OFF connect the injector wiring connectors.
Switch ignition ON and backprobe the control unit wiring connector terminals D15 and D16 with a test lamp to earth.
The test lamp should light when the probe contacts each terminal.
If the test lamp does not light,check the wiring harness for continuity between the injector wiring connectors and the control unit
wiring connector terminals D15 and D16...repair or renew the wiring harness as necessary.
I have power at both sides of the injectors (blue/red) when ignition is on. I don't have power at D15 or D16 (blue wires on ECM).. Someone has soldered a small white plug into these wires?? Check out the pic. Should I run a new D15 wire to injectors? And a new D16 wire to injectors? Does it matter which ones they go to?
