If your car won’t start, it can be both frustrating and inconvenient. Understanding common reasons and troubleshooting steps can help you diagnose and potentially fix the issue yourself. This guide will walk you through the process of identifying the problem and suggest practical solutions.

Why Won’t My Car Start?

When a car won’t start, it typically involves issues with the battery, starter, or fuel system. Here are some common reasons:

• Dead Battery: The most frequent cause of a car not starting.
• Faulty Starter: The starter motor may be malfunctioning.
• Fuel System Issues: Problems with fuel delivery can prevent starting.
• Ignition Switch Problems: A faulty ignition switch can disrupt the starting process.

How to Diagnose a Car That Won’t Start

Step 1: Check the Battery

• Inspect Battery Terminals: Ensure terminals are clean and tight.
• Test Battery Voltage: Use a multimeter to check for at least 12.6 volts.
• Jump Start the Car: If the battery is low, attempt a jump start.

Step 2: Listen for Clicking Sounds
