INSPECT RESISTANCE OF COLD START INJECTOR
(a) Disconnect the cold start injector connector.
(b) Using an ohmmeter, measure the resistance between
the terminals.
Resistance: 2 ± 4

If the resistance is not as specified, replace the cold start
injector.
(e) Reconnect the cold start injector connector.
REMOVAL OF COLD START INJECTOR
1. DISCONNECT CABLE FROM NEGATIVE TERMINAL
OF BATTERY
2. DISCONNECT COLD START INJECTOR CONNECTOR
3. DISCONNECT COLD START INJECTOR PIPE
(a) Put a suitable container or shop towel under the injector
tube.
(b) Remove the two union bolts and four gaskets and injector
pipe. .
HINT: Slowly loosen the union bolt.
4. REMOVE COLD START INJECTOR
Remove the two bolts, cold start injector and gasket.

INSPECTION OF COLD START
INJECTOR
1. INSPECT INJECTION OF COLD START INJECTOR
NOTICE: Keep clear for sparks during the test.
(a) Install SST (two unions) to the injector and delivery
pipe with new gaskets and the union bolts.
SST 09268±41045 (09268±41080)
(b) Connect SST (hose) to the unions.
SST 09268±41045
(c) Connect SST (wire) to the injector.
SST 09842±30050
(d) Put a container under the injector.
(e) Reconnect the battery negative (±) cable.
(f) Turn the ignition switch ON.
NOTICE: Do not start the engine.
2. INSPECT LEAKAGE
(a) In the condition above, disconnect the test probes of
SST (wire) from the battery and check fuel leakage from the
injector.
SST 09842±30050
Fuel drop: One drop or less per minute
(b) Disconnect the battery negative H cable.
(c) Remove SST and the service wire.
SST 09268±41045 and 09842±30050(h) Connect the test probes of the SST (wire) to the
battery, and check that the fuel spray is as shown.
SST 09842±30050
NOTICE: Perform this check within the shortest pos-
sible time.
(g) Using SST, connect terminals +B and FP of the
check connector.
