Fuel Injector Test
- With engine idling or cranking (no start), use stethoscope to listen for consistent, operational sounds (clicking) coming from each injector. If operational sounds are present, go to FUEL INJECTOR LEAKAGE TEST. If operational sounds are not present, remove fuel injector wiring harness connector(s). Using DVOM, check injector resistance. Replace injector if resistance is not within specification. See FUEL INJECTOR RESISTANCE .
- If injector resistance is within specification, connect Fuel Injector Tester/Cleaner (113-00001) to fuel injector wiring harness connector. Start engine. The continuity light should blink, indicating circuit is complete. If light does not blink, check for 12 volts at injector lead. If 12 volts is not present, repair circuit as necessary.
