Car repair

If your car won’t start but the battery is good, and you are looking for reasons as to why it is happening, then you are at the right place.

You make an unsuccessful attempt to start the ignition, yet you find that the vehicle does not start. You find yourself unintentionally stranded in the centre of the street with no knowledge of what is ailing your automobile and no one to help you.

Cars are frequently left stranded because of a weak or dead battery. A car suddenly stopping suggests a problem with the motor, the fuel supply system, the electrical wiring, or perhaps the car battery.

Even though you are not an expert in machinery or fuel supply network topics, you can quickly determine whether your car’s battery needs to be checked.

Why Won’t My Car Start But The Battery Is Fine?

If the car battery is good but not delivering the necessary electricity to start the engine. The issue may be with the motor, wiring, capacitor, or sensors.

In such a scenario where the battery is fine, you should try and repair the starter, inspect the dynamo, ensure the battery is correctly connected, and solve any other electrical concerns. If these solutions do not work, seek assistance from a professional car repair shop.

This article highlights the critical reasons why your car won’t start despite a good battery and the alternatives to choose for the same. Let’s get into the topic now.

5 Reasons Why Your Car Won’t Start If The Battery Is Good?

1. Problems With The Starter Engine:

Reason 1 - Problems With The Starter Engine

The starter is the primary source of trouble; you can detect it under the floor of the car, and you can diagnose the issue else you can visit a car repair shop and get full engine service. Even when you hear a creak, the engine might not operate because the starter does not get enough electricity.

The following are some frequent signs of a malfunctioning starter:

  • Engine Won’t Start

Your inside indicators illuminate, but nothing occurs when you press the key.

  • Crackling Sound

Some people believe that popping is a sign of a bad starter, but it might also be a sign of a bad battery. On the other hand, a low humming or whining sound indicates that the engine is trying, but the generator is too low to turn the engine.

  • Problems Starting Intermittently

If your car did not start, you left it for a bit and then returned, and it started well; this is a powerful indicator that the ignition relay is reducing its capacity to deliver a constant signal.

  • Smoke

You again try to start it, but the electrical system might overheat and produce smoke due to a blown transformer or short circuit. Starters will degrade with time. If your automobile is more than ten years old and still running on its original starter, replacing it is the only option. This duration may be short in colder climates when the starter has to work harder to start the car in the morning.

2. The Battery Is Connected Imperfectly

Reason 2 - Car Battery is Connected Imperfectly

A weak connection is not just one of the biggest reasons for a car not starting, but it is also among the most missed. If your barry is not correctly connected, it car will not receive adequate power. Consequently, when you switch on the switch, no electricity flows through it, and your automobile will not start or stay switched on.

3. The Awful Ignition Switch

Reason 3 - Faulty Car Ignition Switch

The ignition switch, often known as the starter button or start switch, is in charge of igniting the vehicle’s major power equipment. When you flip the key, and none happens—even from the car’s internal electrical components—this is a clear symptom of a faulty ignition switch. However, it can be hard to differentiate from a power or starting problem. As an outcome, the symptoms listed below are frequently associated with a malfunctioning ignition switch.

If the key doesn’t turn – The ignition switch has four settings. 1) lock, 2) auxiliary, 3) turn on, and 4) start. If you press a key and cannot access each location, it is usually related to a faulty ignition switch.

When you press the key, a malfunctioning ignition switch might prevent the automobile from commencing and keep it powered up. The primary sign of an electrical issue is that the ignition will turn on, but nothing else happens; amenities such as electric windows and headlights will not turn on. It might be due to switch corrosion or technical issues such as damaged or shorted cables. To get your car going again, a certified specialist must determine and correct any faults with the ignition system.

4. Gasoline

Reason 4 - car gasoline

If you feel that the problem is caused by gasoline, you must try some methods. If the weather has been freezing, your gasoline line may have stopped and need to be released. The following are two other frequent solutions:

  • The Gas Tank Is Empty

Even though your tank does not seem to be empty, that may not be the case. You can run out of gasoline because of a malfunctioning fuel gauge.

  • Replace The Fuel Pump

Gas cannot flow into the engine because the fuel sensor is clogged. Your gasoline filter may seem noticeably worn out if you regularly run your car to dry. Consult your manual to learn how often or how recently your gasoline filter needs to be changed.

The gasoline tank’s fuel pump does what it sounds like it does. It transports fuel from the fuel tank to the engine through the fuel lines. A failing fuel pump, which is far more problematic than a blocked fuel filter, is one of the worst-case situations for a car that won’t start since most fuel pump repairs cost well over $500.

While the problem is severe, a malfunctioning fuel pump may be diagnosed relatively quickly by a layperson. When you switch on your ignition and the fuel system is running correctly, you may hear a mild whirring for 1-2 seconds. It is the sound of the fuel pump delivering fuel to the engine.

5. Car Electrical Problems

Reason 5 - Car Electrical Problems

Electrical difficulties in the vehicle might cause a car not to start. It can be caused by faulty fuses and relays, and improperly grounded electrical components (such as rusty grounding points), etc.

Car Won’t Turn Over But Has Power

Car Won't Turn Over But Has Power

A car that won’t start when you require it can be quite a nightmare. Nothing beats walking out the door, ready to face the day, only to discover that your car won’t start, even though it’s got the battery.

However, if your car retains electricity, the issue is unlikely to be related to the battery. However, the battery’s capacity to store a charge varies. You can also look for a lousy alternator, a defective starting system, or a damaged fuel pump.

We’ve all experienced a dead battery pack that prevents the vehicle from starting. However, the problem isn’t with the alternator if the car won’t start but has electricity.

Car Has Power But Won’t Start Just Clicks

Car Has Power But Won't Start Just Clicks

You are most likely correct. The dreadful clicking noise is generally the power, and the solution might be as easy as a jump start or fixing a wire. However, a single click indicates that the problem is most likely with the starting engine.

Here’s what to check for if you hear fast clicking:

The Battery Has Died

Dead Car Battery

Did you also switch on an interior light or a spotlight while you slept to deplete the battery? If so, a set of adapters and perhaps another car with a dependable charger should allow you to swiftly get back on the road.

Corrosion, Cables, And Connections

Corroded car battery

The cables need to be tightened because they might have become loose from road shocks and are not regularly establishing good electrical contact. If the terminals have corroded, removing the wires and wiping off the gunk may reestablish proper connections.

Car Won’t Start But Radio Works

Car Won't Start But Radio Works

When the pressure in the gasoline transmission system is low, fuel pump difficulties might arise. It can be caused by line wear and tear, obstructions, or leaks. If it fails, the car will not start, but the stereo and lights will continue functioning.

How Do You Know If It’s A Starter Or Battery Problem?

Car Battery Failure

People tend to think that all of their vehicle’s components will function correctly, but the battery is sure to be the first one to fail. Examine the electrical connections for corrosion. Remove them with metal or a bristle brush before attempting to restart your automobile. The problem might be with the starter if it still doesn’t work.

Poor Starter

A broken starter sounds very similar to a dead battery – when you turn the key, and all you notice is a click. The problem might be the poor starter. However, the solenoid may be malfunctioning rather than the starting mechanism as a whole. It hinders the starter from producing the necessary electricity to start your vehicle.


If you’ve witnessed a situation where the car won’t start but the battery is good, you must check the car yourself. If you are not able to figure it out, you can call a mechanic to investigate. While you may believe the battery is not to blame, some batteries contain a modest charge sufficient to create some electrical components but not the engines.

There are several reasons why your automobile won’t start. However, if the battery is fine, despite troubles with the battery itself, the starter, its ignition switch, the fuses, and eventually, there might be issues with the fuel system. Regardless of the cause of the starting issue, you would have to get it repaired as quickly as possible to prevent being stranded on the road.
