Cold Start Valve (Except Vanagon)
- Engine temperature must be below 85°F (30°C). Disconnect cold start valve attaching screws and remove valve leading wiring harness connector and fuel line attached.
- Remove ignition coil secondary wire and jumper to ground. Attach metal housing of cold start valve to ground. Direct cold start valve nozzle into a clean container. See Fig 1
. Have assistant turn ignition switch to the "START" position while observing spray pattern.
- The valve should deliver a consistent cone shaped pattern until the thermo time switch interrupts fuel flow. Ensure that valve does not leak after fuel flow stops. If spray pattern is uneven or inconsistent, check for plugged or defective cold start valve. If valve does not function, proceed to THERMO TIME SWITCH.
