A hung start is characterized by which condition?

Explanation:
A hung start means the engine lights off—fuel ignites—but it does not accelerate to normal idle speed, so the RPM stays at a low value. This is why the correct description is a normal light-off with the RPM remaining low, signaling you should shut the engine down to prevent damage and try again. The other scenarios describe a hot start (excessive EGT), a normal start (RPM climbs to idle), or no light-off (no ignition).
