The engine may experience low power.    Perform this procedure under conditions that are identical to the conditions that exist when the fault occurs. Typically, faults with the injector solenoid occur when the engine is warmed up and/or when the engine is under vibration (heavy loads).These engines have Electronic Unit Injectors (EUI) that are mechanically actuated and electronically controlled. The ECM sends a pulse to each injector solenoid. The pulse is sent at the correct time and at the correct duration for a given engine load and speed. The solenoid is mounted on top of the fuel injector body.If an open circuit is detected in the solenoid circuit, a diagnostic code is generated. The ECM continues to try to fire the injector. If a short circuit is detected, a diagnostic code is generated. The ECM will disable the solenoid circuit. The ECM will periodically try to fire the injector. If the short circuit remains this sequence of events will be repeated until the fault is corrected. When an injector is replaced, program the new injector code into the ECM. If the ECM is replaced, all of the injector codes must be programmed into the new ECM. Refer to service Troubleshooting, "Injector Trim File -Install".Note: Discard all fuel injection lines after use. Fuel injection lines must only be used one time.The Caterpillar Electronic Technician (ET) includes the following tests that aid in troubleshooting the injector solenoids:"Cylinder Cutout Test"All active diagnostic codes must be repaired before running the "Cylinder Cutout Test". Use the "Cylinder Cutout Test" to diagnose a malfunctioning injector while the engine is running. When a good injector is cut out, the "Fuel Position" should change. The change in the fuel position is caused by the
