What Are the Reasons Why a Car Cannot Start with a Jump Start?

[MacLucas]

Here is the relevant introduction to why a car cannot start with a jump start: It may be due to severe power loss in the old battery, jumper cables being too thin resulting in insufficient current to start the car, or the clamps of the jumper cables not being properly attached. Below is the relevant introduction to handling a car that won't start due to a dead battery: 1. Push Start Method (only for manual transmission cars): Push the car to a certain speed, then engage the gear and quickly release the clutch pedal while stepping on the accelerator. Once the engine starts, quickly press the clutch pedal again, control the throttle to prevent the engine from stalling, and then slowly pull over to park. 2. Jumper Cable Method: First, find a nearby car with a charged battery and a set of jumper cables. Bring the two cars close together, open the hood to locate the other car's battery, and then connect the two batteries with the jumper cables—positive to positive and negative to negative.
