SWITCH ES
FUEL PUMP RELAY
Remove the fuel pump relay from the mount braket.
Check for a burnt sub-fuse.
Check the relay ·coupler for improper contact and
looseness. Measure the voltage between the relay
black wire and a body ground. The battery voltage
should reqi ster with the ignition switch ON.
Make sure that the fuel pump operates while the
relay coupler black and white wires are shorted and
the ignition switch is ON.
If the pump does not operate, check the fuel pump
coupler for improper contact and the fuel pump

Check for cotinuity between the ignition control
unit blue wire and fuel pump relay coupler blue
wire. If there is continuity, replace the fuel pump
relay. If there is no continuity, replace the wire
harness.
THERMOSTATIC SWITCH
The cooling fan motor is actuated by the thermo-
satic switch located in lower the radiator.
If the fan motor does not start, disconnect the
switch coupler from the thermostatic switch and
short coupler terminals together with a jumper wire
as shown.
Turn the ignition switch on.
The cooling fan motor should start running.
If
it does not start, check for battery voltage from
the black lead (positive) to black/blue (negative) of
the fan motor coupler.
If there is no voltage, check for a blown or faulty
fuse. loose terminals or connectors, or an open
circuit.
