Test each injector two or three times. SST 7M·GE 09842-30070 7M·GTE 09842-30060 Injection volume: 7M·GE 69 — 85 cc (4.2 — 5.2 cu in.) per 15 sec. 7M·GTE 101 — 114 cc (6.2 — 7.0 cu in.) per 15 sec. Difference between each injector: 9 cc (0.5 cu in.) or less If the injection volume is not as specified, replace the injector. 2. INSPECT LEAKAGE (a) In the condition above, disconnect the test probes of SST (inspection wire) from the battery and check the fuel leakage from the injector. SST 7M·GE 09842-30070 7M·GTE 09842-30060 Fuel drop: One drop or less per minute. (b) Disconnect the battery negative (—) cable. (c) Remove SST.
