Cold Start Injector: Description and Operation
Cold Start Injector
PURPOSE
The cold start injector injects extra fuel into the intake air chamber to enrich the fuel mixture during low temperature cranking.
LOCATION

Operation is controlled by the start injector time switch. At coolant temperatures below 59°F (15°C), starter voltage is passed to the injector. To
avoid engine flooding, operation is typically less than 10 seconds.
