What Are the Reasons Why the Car Still Won't Start Even After a Jump Start?
1 Answers
The reasons why the car still won't start even after a jump start are as follows: 1. Incorrect gear position: When parking and turning off the engine, the gear was not set to P (Park) but left in D (Drive). 2. Out of fuel: Apart from a dead battery, the car won't start if it's out of fuel. 3. Malfunctioning fuel pump. 4. Faulty starter motor. 5. Excessive carbon buildup in the throttle body. 6. Faulty crankshaft position sensor. Solutions for when the car still won't start after a jump start: 1. Jumper cables: These are essential items for jump-starting a car. Never use random wires as a substitute, as the instantaneous current during startup can reach 200-600A (even up to 1000A for diesel vehicles). Only 10-gauge copper cables can ensure a smooth and safe start. Always purchase reputable, high-quality jumper cables—don't compromise on safety to save money. This is a must-have item in your car in case the battery dies. 2. Emergency power supply: This is a new portable device similar to a power bank, available in lead-acid or lithium polymer versions. It can help jump-start a dead battery and often comes with additional functions like lighting, charging mobile devices, and powering air pumps for inflating tires. Compact and lightweight, it eliminates the need to ask others for a jump start. Remember to recharge it promptly after use to ensure it's ready for emergencies. 3. Don't be alarmed by sparks. The reason for not connecting the negative terminal first is that most metal parts of the car are grounded (negative). If the negative is connected first and the positive clamp touches any conductive part of the car body, it could cause a short circuit and damage vehicle components.
