The correct answer is D) Higher than normal temperatures for start up. When attempting to restart a warm high-speed engine, you can expect higher than normal temperatures for start up. This is because the engine components, such as the cylinder walls and pistons, are already warm from the previous operation. As a result, the engine will require less time and effort to reach the optimal operating temperature, leading to higher starting temperatures compared to a cold engine start. The other options are incorrect because: A) Excessive fuel use is not a typical reaction, as the engine management system should adjust the fuel delivery accordingly. B) Higher than normal lube oil pressure is also not a common response, as the oil system is designed to maintain proper lubrication. C) Longer starting periods are not expected, as the warm engine components facilitate a quicker and more efficient restart.
