🔍 Key Concepts

• difference between electrical starting problems and fuel system problems • what it means when an engine can be "barred over" by hand • which systems are involved in cranking versus actual running of a diesel engine

💭 Think About

• Ask yourself: if the engine turns freely by hand but will not crank on the starter, which system is most likely at fault: electrical, fuel, or lubrication/governor? • Consider which of these choices would prevent the starter from rotating the engine at all, as opposed to preventing it from firing and running. • Think about the symptoms you would see with fuel problems versus battery or connection problems.

✅ Before You Answer

• Be clear on the difference between cranking (starter motor action) and starting/running (fuel combustion). • Identify which of the listed issues would directly affect starter motor power rather than fuel delivery or speed control. • Eliminate any option that would allow normal cranking but prevent the engine from firing.
