Question

Long periods of cranking an engine can waste fuel, therefore you should:

A. stop and wait a couple of minutes before trying again if the vehicle's engine does not start after 30 seconds of cranking.
B. pump the accelerator or rev the engine after it starts to reduce the chances of the engine dying.
C. travel at maximum speed once in motion to decrease fuel use and air resistance.
D. all of the above.

Answer 1

Long periods of cranking an engine can waste fuel. The best option is to stop and wait a couple of minutes before trying again if the vehicle's engine does not start after 30 seconds of cranking.

Step-by-step explanation:

Long periods of cranking an engine can waste fuel because the engine continues to consume fuel even if it doesn't start. Therefore, the best option is to stop and wait a couple of minutes before trying again if the vehicle's engine does not start after 30 seconds of cranking. Pumping the accelerator or revving the engine after it starts is not recommended as it can actually increase fuel consumption and damage the engine. Traveling at maximum speed once in motion does not decrease fuel use and air resistance; instead, it can significantly increase fuel consumption due to increased drag.
