Disconnect the electrical connector from the cold start injector, noting that the wire clip must be expanded before unlocking the plug from the injector terminal. Ground the connector with a test light and turn the ignition key to Start; the light should illuminate if the circuit is functioning properly. If it does not, inspect the cold start injector electrical circuit for any issues such as an open, short, or bad connection. Remove the two mounting bolts and pull the injector out of the plenum without disconnecting the cold start tube banjo fitting. Reconnect the electrical connector to the injector, place a small container underneath, and turn the ignition key to Start; if the injector is working correctly, it will squirt fuel into the container. If it does not, it needs to be replaced. Disconnect the electrical connector again and check the injector for continuity with an ohmmeter, ensuring the resistance between terminals is between 3 to 5 ohms; if not, replace the injector. Temporarily install the injector mounting bolts, then use a backup wrench to break loose and disconnect the cold start injector tube banjo fitting. Disconnect the electrical connector, remove the two mounting bolts, and take out the injector. Installation follows the reverse order of removal.
