Cold Start Injector
- Disconnect negative battery cable. Disconnect cold start injector wiring harness connector. Check resistance between terminals of injector. Replace injector if resistance is not 2-4 ohms. If resistance is okay, relieve fuel system pressure.
- Remove cold start injector from vehicle. Install fuel hose to injector. Install system Union Adapters (9268-41045) to delivery pipe and cold start injector. Connect fuel hose to union adapters. See Fig 1. Connect Jumper Harness (9842-30050) to cold start injector.
- Place container under cold start injector. Connect jumper wire to engine check connector terminals FP and B+ to pressurize fuel system. For engine check connector locations, See Figure. Turn ignition on, with engine off.CAUTION: Perform cold start injector connector test in shortest possible time.
- Connect probes of Fuel Injection Tester (09842-30070) to battery. Connect other end of tester to cold start injector. See Fig 1. Ensure fuel spray is an even cone shape.
- Disconnect fuel injector tester harness and observe cold start injector. Maximum leakage should be one drop per minute with fuel pressure applied. Clean or replace cold start injector if defective.
NOTE:
Cold start injector is controlled by cold start injector time switch when ignition switch is turned on.
