Fuel Injector

On sequential PFI engines, disconnect injector harness connectors. Using digital ohmmeter, check connector terminal resistance of each injector. If resistance is not 11-18 ohms, replace injector. On non-sequential PFI engines, disconnect injector bank harness connector. Check resistance of injector bank. See INJECTOR BANK RESISTANCE table. Repair wiring or any injector not within specification.
