Fuel Injector Resistance (Except Millenia)

WARNING: This page is about a different car, the 2000 Mazda Protege, 2000 Mazda Millenia, 2000 Mazda MX-5 Miata, 2000 Mazda MPV, and 2000 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect fuel injector connector. Using ohmmeter, measure resistance between injector terminals. Resistance should be about 13.8 ohms (Protege 1.6L) or 12-16 ohms (all others). Replace injector as necessary.
