* Battery condition: A weak battery will require more cranking.
* Starter motor condition: A worn starter motor will crank slower.
* Engine temperature: Colder temperatures will require more cranking.
* Oil viscosity: Thicker oil (especially in cold weather) increases cranking resistance.
A healthy engine and battery system in moderate temperatures should start within 2-3 seconds of cranking. If it takes significantly longer (more than 5-7 seconds) or doesn't start after several attempts, there's likely a problem that needs attention, such as a weak battery, faulty starter, or other engine issue. Don't keep cranking excessively, as this can damage the battery and starter.
