Cold Start Valve
- Check cold start valve with engine coolant temperature below 86°F (30°C). Disconnect and ground high tension lead at distributor cap end. 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 allowed by ECU. If no fuel sprays and fuel pressure is present, test system control in TESTS W/CODES article in this section. Dry off tip and check for leaks. Acceptable leakage rate of cold start valve is one drip per minute or less.
