TM 5-4320-305-24 Table 2-2.  Organizational Maintenance Troubleshooting - Continued MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION 3.  ENGINE RUNS UNSTEADILY AND POWER OUTPUT IS LOW Step 1.  Check air cleaner intake restriction indicator for red band indicating blocked air cleaner elements. If red band appears in air cleaner restriction indicator and rain cap is not blocked and no damage to system components is found, replace primary and secondary elements (para 2-26). Step 2.  Be sure that fuel tank fill cap vent is in open position.  A closed vent will cause a vacuum in the fuel tank and not allow fuel to flow freely to the fuel feed pump. If vent is in closed position, rotate cap vent to open position. Step 3.  Check fuel supply to injectors. If there is no fuel flow, replace fuel filter and clean fuel feed pump strainer as described in paragraphs 2-30 and 2-32. Step 4.  Check air inlet and turbocharger for obstructions, carbon or dirt buildup on turbocharger impellers, or oil leaks. Notify direct support. Step 5.  a.    Check  quick  release  link  and  lever  extension  for  dirt,  corrosion,  damage,  or  loose  nuts,  washers, bolts, screws, and quick disconnect fittings. Clean; tighten hardware and quick disconnect fittings.  Replace if severely damaged (para 2-24), b.  Remove and check throttle actuator. Replace defective throttle actuator (para 2-24). Step  6.    Check  magnetic  pickup  wiring  for  continuity,  breaks,  burrs,  or  fraying.    Check  for  loose  or  damaged connectors. Replace wires or connectors if broken or damaged (para 2-15 and 2-16). Step 7.  Notify direct support. 2-28
