• Ignition off
• Check the injector connector. Check for contact resistance and oxidation
• Reinstall the components, reconnect the connectors etc.
• Ignition on
• Activate the injector.

  A "click" should be heard when the injector is activated.

  If the injector is now OK, the fault was caused by poor contact in the connector.
