What is a hard start and how does it impact the performance of a vehicle?

A hard start is when a vehicle has difficulty starting or takes longer than usual to start. This can be caused by issues such as a weak battery, faulty starter motor, or fuel system problems. A hard start can impact the performance of a vehicle by causing it to run rough, have reduced power, or even stall while driving. It can also lead to increased fuel consumption and potential damage to the engine over time.
