Fuel Injectors (Camry CNG Models)
- To check for fuel injector operation, using stethoscope, listen for clicking sound at each fuel injector, or feel for fuel injector operation at fuel injector with engine cranking or with engine running. If fuel injector operation does not exist, check for loose connection at electrical connector for fuel injector. If electrical connector at fuel injector is okay, go to next step.
- Ensure ignition is off. Disconnect electrical connector at fuel injector. Using ohmmeter, check resistance between electrical terminals on fuel injector. Replace fuel injector if resistance is within specification. See FUEL INJECTOR RESISTANCE table. If fuel injector resistance is within specification but fuel injector does not operate, it may be necessary to check fuel injector circuit. See FUEL INJECTOR CIRCUIT under COMPUTERIZED ENGINE CONTROLS.
