Question

If the starter "whines" when engaged, which of these is a possible cause?

1) Battery is dead
2) Fuel pump is failing
3) Spark plugs are worn out
4) Alternator is malfunctioning

Answer 1

A whining starter motor is likely indicative of a dead battery, as the starter requires sufficient power to turn over the engine.

Step-by-step explanation:

If the starter "whines" when engaged, a possible cause could be that the battery is dead. A starter motor needs a strong current from the battery to turn the engine over. If the battery is weak or dead, it might not provide enough power to the starter, resulting in a whining noise as it tries to turn. The other options listed, such as a failing fuel pump, worn-out spark plugs, or a malfunctioning alternator, are less likely to be related to the starter motor's noise. These components are involved in different stages of the vehicle's operation and would present different symptoms if they were failing.
