Fuel Injector Test: 200SX

  1. With engine running, listen for clicking sound at each injector. If clicking sound is present at each injector, system is functioning properly. If clicking sound is not present, turn ignition off.
  2. Disconnect injector harness connector(s). Turn ignition on. Measure voltage between ground and injector harness connector Black/Red wires (White wire on 2.0L engine). Battery voltage should be present.
  3. If battery voltage is not present, check 30-amp fusible link and ignition switch. If fusible link and ignition switch are okay, repair or replace harness or connectors. If battery voltage is present, check fuel injector. See FUEL INJECTOR. If fuel injector is okay, check ECM terminals, harness and connector terminals for damage or corrosion. Repair or replace as necessary.
