Testing of the fuel injector circuit refer to CHART A-3 with additional diagnosis refer to CHART A-4. Refer to A Charts. Under Computer and Controls/System Diagnosis/Procedures. 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."
