Cold Start Injector

Engine must be cold to perform this test. Remove electrical connector from cold start injector and connect voltmeter across connector terminals. Crank engine. Battery voltage should be present.
Release fuel system pressure and remove cold start injector with fuel lines attached. Reconnect electrical connector and place injector in container.
As cold engine is cranked, fuel spray should be observed until thermo time switch cuts off relay. When engine is warm, no fuel spray should occur during cranking. If injector does not respond as outlined, replace cold start injector.
