Cold Start Valve: Toyota
- Remove cold start injector from inlet chamber with fuel lines and coupler connected. Remove coupler and install test coupler to valve. Position cold start valve in glass container and keep valve away from electrical connectors.
- Turn ignition switch "ON" but do NOT start engine. Connect jumper wire to fuel pump check connector terminals (located in wiring harness near air flow meter). Connect test coupler to battery voltage. Fuel should be injected.
- Disconnect test coupler from battery and check that valve does not leak fuel. Remove jumper wire at fuel pump check connector and test coupler from valve. Connect ohmmeter to cold start valve terminals and check for 3-5 ohms. If cold start valve does not perform as described, replace cold start valve.
