Fuel Injector Circuit

Disconnect injector harness connectors. Using digital ohmmeter, check connector terminal resistance of each injector. Individual injector resistance should be 13-16 ohms on all models. 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.
