Fuel Injectors
- Unplug fuel injector harness at injector. Using ohmmeter, measure resistance across terminals. Replace fuel injectors if resistance is not within specification. See FUEL INJECTOR RESISTANCE SPECIFICATIONS table.
- With engine running, check fuel injector operating noise. Normal operation of injectors is indicated if a regular click is heard, which varies with engine speed. If click is not heard, replace injector.
