- Warm up engine and allow it to idle. Using screwdriver or stethoscope, listen to each injector. Clicking sound should be heard. If no sound is heard, measure resistance of suspected fuel injector. See FUEL INJECTOR RESISTANCE SPECIFICATIONS table. See Fig 1. Replace injectors that do not meet specification. To replace fuel injectors, see FUEL DELIVERY PIPE & INJECTORS under FUEL SYSTEM in REMOVAL, OVERHAUL & INSTALLATION article. If injectors are okay and no operational sound is heard, go to next step.
- Check wiring to injectors for an open or short circuit, repair as necessary. Ensure electrical connectors fit tightly and are not corroded. For circuit testing, see appropriate WIRING DIAGRAM under ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS.
