Fuel Injector Resistance
WARNING: This page is about a different car, the 2003 Mazda Tribute, 2003 Mazda B4000, 2003 Mazda B3000, and 2003 Mazda B2300. However, it is still accessible from the selected car via links, so may be relevant.
Disconnect fuel injector 2-pin harness connectors. Using a DVOM, measure resistance between injector terminals. See FUEL INJECTOR RESISTANCE table. If resistance reading of any injector is not as specified, replace faulty fuel injector. If resistance reading is as specified and problem is still present, check fuel injector circuit. For additional testing, refer to appropriate SELF-DIAGNOSTICS article.
