How long should you allow between cranking attempts?

• A. Five minutes
• B. One minute
• C. Two minutes
• D. Thirty seconds

Answer: (C)

Resting between cranking attempts protects the starting system and improves the chance the engine will catch. Cranking draws a lot of current from the battery and can overheat the starter motor if done repeatedly. A two-minute pause allows the starter to cool and the battery voltage to rebound, so you have enough cranking power for the next attempt. It also gives the fuel system time to stabilize and the engine electronics to reset. Shorter pauses can leave the starter hot and the battery drained, while waiting longer than needed wastes time.
