- Warm up engine and let idle. Using screwdriver or stethoscope, listen to each injector. Clicking sound should be heard. If no sound is heard, measure resistance of each injector. See Fig 1. Replace injectors that do not meet specification. To replace injectors, see appropriate FUEL DELIVERY PIPE & FUEL 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. Ensure electrical connectors fit tightly and are not corroded. For circuit testing, see WIRING DIAGRAMS article.
