Cold Start Valve
- Ensure engine coolant temperature is less than 86°F (30°C). Disconnect and ground coil secondary wire at distributor cap. Remove cold start valve from intake manifold with wiring and fuel line connected. Point tip into safe container.
- Crank starter for 10 seconds. Valve should emit cone-shaped spray for time duration allowed by ECU. If there is no fuel spray and fuel pressure is present, test system control. See TESTS W/CODES
article in the ENGINE PERFORMANCE Section. Dry tip and check for leaks. Acceptable leakage rate of cold start valve is one drip or less per minute.
