Pulse Relay & Cold Start Valve

Disconnect high tension wire 4 from distributor and connect to ground. Remove cold start valve, but leave fuel line and wiring connected. Point valve into container.
With engine coolant below 90°F (35°C), crank engine with starter. Valve should spray for 1-8 seconds in cone-shaped pattern, then stop spraying momentarily. Valve should continue to spray periodically in pulses as starter is operated.
With engine warmed up, valve should spray fuel after 2 seconds, then stop. It will begin to spray periodically in pulses if the engine is still cranked.
If spray does not pulse, check for open or shorted wires. If wiring is good, replace pulse relay.
