Injector Circuit

WARNING: This page is about a different car, the 1991 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect all injector harness connectors. Using digital ohmmeter, check resistance across terminals of each injector. See appropriate injector resistance table.
On models without Sequential Electronic Fuel Injection (SEFI), disconnect injector bank harness connector, check resistance of injector bank. See INJECTOR BANK RESISTANCE table. Injectors on SEFI models have each individual injector wired to the ECA. Repair wiring or replace any injector circuit not within specification.
