Fuel Injector: Testing and Inspection
Fig. 10 Fuel Injector Internal Components - Typical
To test the injector only, disconnect the fuel injector wire harness connector from the injector. Place an ohmmeter across the injector terminals.
Resistance reading should be approximately 12 ohms +/- 1.2 ohms at 20°C (68°F).
CAUTION: Do not leave electrical current applied to the injector for longer than five seconds. Damage to injector coil or internal injector seals (Fig.
10) could result.
