The engine exhaust has too much black smoke. The engine has lost power and the engine uses too much fuel. The engine is misfiring, running rough, or running poorly. Troubleshooting Fuel Injection Nozzles on a Nozzle Tester Back leakage The fuel injection nozzle does not inject fuel in the correct quantity or in the correct pattern. Troubleshooting the Engine

The engine will not start. The engine starts and the engine runs for a brief period of time and the engine stops. The engine misfires or the engine runs rough. The engine runs evenly, but the engine loses power. The engine lacks power. The engine has excessive vibration. The engine has excessive combustion noise. The engine has excessive valve compartment noise. Engine oil is in the cooling system. Engine knock occurs. The rocker arm has insufficient movement and the valve lash exceeds the specification. A cylinder head valve is loose. Oil condenses at the exhaust. The valve lash is less than the required specification. Engine components have early wear. Coolant is in the engine oil. The engine exhaust has too much black smoke or too much gray smoke. The engine exhaust has too much white smoke or too much blue smoke. The engine has low oil pressure. The engine oil pressure is too high. The engine uses too much engine oil. The engine overheats. The exhaust temperature is too high. The starting motor does not turn or the starting motor turns too slowly. The starting motor turns, but the pinion gear does not engage the flywheel ring gear. The engine does not crank or the engine rotates slowly when the keyswitch is in the start position. The starting motor continues to run after the ignition switch is released. The pinion gear does not disengage after the engine starts to run. The alternator does not charge the battery or the alternator charge rate is slow or irregular. The alternator charges the battery to a voltage that is too high. The alternator is noisy.
