Fuel Injector: Testing and Inspection

Testing of the fuel injector circuit is located in the Engine Cranks but Does Not Run with additional diagnosis in the Injector Circuit Diagnosis. Refer to System Diagnosis / Diagnostic Tables. Testing and Inspection

A fuel injector which does not open may cause a no-start condition. An injector which is stuck partially open could cause loss of pressure after sitting, resulting in extended crank times on some engines. Also, dieseling could occur because some fuel could be delivered to the engine after the key is turned OFF.
