REMOVE COLD START INJECTOR FROM AIR INTAKE CHAMBER INSPECTION OF COLD START INJECTOR 1. MEASURE RESISTANCE OF COLD START INJECTOR Using an ohmmeter, check the resistance of the injector. Resistance: 3 — 5 Ω 2. CHECK INJECTION OF COLD START INJECTOR (a) Install the gasket, SST (two unions), another gaskets and two union bolts to the delivery pipe and injector. SST 09268-41045 (b) Connect the SST (hose) from the unions. SST 09268-41045 (c) Connect the SST (wire) to the injector. SST 09842-30050 NOTE: Position the injector as far away from the battery as possible. (d) Put a container under the injector. (e) Turn on the ignition switch. NOTE: Do not start the engine. (f) Short both terminals of the fuel pump check connector with a service wire. (g) Connect the test probes of the SST to the battery and check that the fuel spray is as shown. SST 09842-30050 NOTE: Perform this check within the shortest possible time. (h) Disconnect the test probes from the battery and check that fuel does not leak from the injector. Fuel drop: Less than one drop of fuel per minute (i) After checking, restore the following to the previous state. • Fuel pump check connector • Ignition switch • SST • Cold start injector • Injector gasket
