Why is my car not cranking but not starting?
Few things are as frustrating as turning the key in your car's ignition, only to hear silence or a faint clicking sound. If your car isn't cranking but also isn't starting, it could be due to a variety of issues. As an experienced auto repair professional at Kevin's Autos, I’ve seen this problem countless times. Let’s dive into the potential causes and what you can do about them.
Understanding the Problem
When your car doesn’t crank, it means the engine isn’t turning over. This is different from a situation where the engine cranks but doesn’t start. The issue could stem from electrical, mechanical, or fuel-related problems. Below, I’ll outline the most common reasons for this issue and how to address them.
Common Reasons Your Car Won’t Crank
- Dead or Weak Battery: The most common culprit is a dead or weak battery. If your battery doesn’t have enough charge, it won’t provide the power needed to crank the engine.
- Faulty Starter Motor: The starter motor is responsible for turning the engine over. If it’s damaged or worn out, your car won’t crank.
- Bad Ignition Switch: A faulty ignition switch can prevent the electrical signal from reaching the starter motor.
- Corroded or Loose Battery Connections: Corrosion or loose connections at the battery terminals can disrupt the flow of electricity.
- Blown Fuse or Relay: A blown fuse or a faulty starter relay can interrupt the electrical circuit needed to start the car.
- Security System Issues: Some cars have anti-theft systems that can disable the starter if they detect a problem.
Steps to Diagnose the Issue
Before heading to the repair shop, you can try a few simple steps to identify the problem:
- Check the Battery: Look for signs of corrosion on the terminals and ensure the connections are tight. If you have a multimeter, test the battery voltage. A healthy battery should read around 12.6 volts when the car is off.
- Listen for Sounds: When you turn the key, listen for a clicking sound. A single click might indicate a faulty starter, while rapid clicks often point to a weak battery.
- Inspect the Fuses: Locate the fuse box and check for any blown fuses related to the starter or ignition system.
- Try Jump-Starting: If you suspect the battery is the issue, try jump-starting the car. If it starts, the battery or alternator may need attention.

Frequently Asked Questions
Will a bad starter still crank?
Engine Won't Crank or Start
The most obvious sign of a bad starter is an engine that won't crank or start. Of course, there are many other issues besides a bad starter that can prevent the engine from cranking. A few examples include a bad battery, failed ignition switch, or an engine mechanical problem.
Why is my engine not cranking when I turn the key?
- Weak Battery : A weak or dead battery is the most common reason.
- Poor Battery Connections : Corroded or loose battery terminals can prevent proper electrical flow.
- Faulty Starter : The starter motor itself might be faulty.
- Bad Ignition Switch
- Faulty Relay or Fuse
- Neutral Safety Switch
- Electrical Issues
What stops an engine from cranking?
The simplest cause of this sort of fault is a loose or corroded electrical connection. If there is a fault with the internal windings of the starter motor, bad brushes, or other electrical faults, the starter motor may lack the torque to crank the engine.
Why is my car not cranking and not starting?
Your car battery is weak or the battery terminals are loose, which is the main cause of a car that won't start the first time. A malfunctioning starter might also be the problem, however, if the engine cranks but won't start, the problem might be a blocked fuel filter or a damaged spark plug.
What to check if car is cranking but not starting?
First, Check the Basics - The very first step to diagnose a “cranks but won't start” problem is to find if something's missing – Spark, Fuel and Compression (which includes cam timing). These three things are required for an engine to start.
Why does my car have full power but won't start?
Why won't my car start but I have power? If you attempt to start up your car but the engine won't turn over and the dashboard lights up, then you most likely have an issue with your battery. You could have a damaged or corroded battery terminal, which is stopping the engine from starting up when you fully turn the key.
What are the signs of a bad spark plug?
What are the signs your Spark Plugs are failing?
- Engine has a rough idle. If your Spark Plugs are failing your engine will sound rough and jittery when running at idle.
- Trouble starting. Car won't start and you're late for work… Flat battery?
- Engine misfiring.
- Engine surging.
- High fuel consumption.
- Lack of acceleration.
How to tell if battery or alternator?
The best way of checking this is to reach for your jumper cables and attempt a jump-start. If, when attempting a jump-start, it stays running for a while but then again fails to start the next time you try, it is probably a battery issue. If it immediately stalls, it is more likely to be a problem with the alternator.
What does it mean when my car wont start but the battery is still alive?
Bad alternator
Connected to the battery is the alternator, which works to generate power for your vehicle's electrical components. When you have a brand-new battery but still can't start the car, the alternator might be the issue. Cold and damp climates may increase wear on an alternator, causing it to fail.
How do you tell if it's a bad battery or starter?
As long as that alternator is creating electricity and the battery is good, your car should start and stay running. If the vehicle won't crank or start but the headlights are still working, look to problems with the starter or other parts of the engine.
