Cold Start

Cold start valve operation is dependent on coolant temperature and cranking signal. Duration of cold start injection is in direct relation to coolant temperature. Should engine start before cold start valve completes its cycle, cold start injection is canceled. Voltage is supplied by fuel pump relay.
