INSPECTION OF COLD START INJECTOR
1. (7M-GTE)
INSPECT RESISTANCE OF COLD START INJECTOR
Using an ohmmeter, check the resistance of the injector.
Resistance: 2 - 4
n
If the resistance is not as specified, replace the cold start
injector.
2. INSPECT INJECTION OF COLD START INJECTOR
CAUTION: Keep clear of 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, 90405-09015)
(b) Connect the SST (hose) to the unions.
SST 09268-41045
(c) Connect the SST (wire) to the injector.
SST 09842-30050
(d) Put a container under the injector.
(e) Reconnect the battery negative (-) terminal.
(f) Turn the ignition switch ON.
HINT: Do not start the engine.
(g) Using SST, connect terminals
+
Band Fp of the check
connector.
SST 09843-18020
(h) Connect the test probes of the SST (wire) to the bat-
tery, and check that the fuel spray is as shown.
SST 09842-30050
NOTICE: Perform this check within the shortest possible
time.
3. 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 (-) cable.
(c) Remove SST.
