(7) Attach the other jumper wire (12V + ) to termi
nal number 86. This will activate the relay. Continu
ity should now be present between terminals number
87 and 30. Continuity should not be present between
terminals number 87A and 30.
(8) Disconnect jumper wires from relay and 12
Volt power source.
If continuity or resistance tests did not pass, re
place relay. If tests passed, refer to Group 8W, Wir
ing

STARTER MOTOR RELAY TEST
Refer to Group 8A, Battery/Starting/Charging Sys
tem Diagnostics, for starter motor relay testing.
FUEL INJECTOR TEST
Disconnect the fuel injector wire harness connector
from the injector (Fig. 36). Place an ohmmeter across
the injector terminals. Resistance reading should be
approximately 14.5 ohms ±1.2 ohms at 20°C (68°F).
Proceed to following Fuel Injector diagnosis chart.
