Is Secondary Ignition Harmful to the Car?

[MicahRose]

Secondary ignition is not significantly harmful to the car. Below is a relevant introduction on how to handle a situation where the battery is dead and the car won't start: Push-Start Method (only for manual transmission vehicles): Push the car to a certain speed, then shift the gear lever into gear and quickly release the clutch pedal while applying throttle. Once the engine starts, promptly depress the clutch pedal and control the throttle to prevent the engine from stalling, then slowly pull over to park. Jump-Start Method: First, find another car with a charged battery nearby and a set of jumper cables. Bring the two cars close together, open the hoods to locate the other car's battery, then connect the two batteries using the jumper cables—positive to positive and negative to negative.
