Fuel Injectors
- Disconnect fuel injector connector. Connect DVOM between ground and terminal No. 2 of fuel injector connector. See Figure . Turn ignition on and check voltage supply to fuel injector. If battery voltage is not indicated, check Red/White wire back to fuse/relay block. See WIRING DIAGRAMS article in the ENGINE PERFORMANCE Section.
- If battery voltage is present, use DVOM to measure resistance across injector terminals. If resistance is not approximately 16 ohms, replace injector. Repeat test for each injector.
