Why won't my 2021 Honda Civic start? ›

The number one reason your Honda won't start is likely the battery. There are many issues that can cause a battery to die, such as corrosion around the connections, bad wiring, or simply age. If a jump-start won't fix this issue, it may be time to get your battery replaced.

Interior Fuse Box

Located under the dashboard.

The main fuse box is typically located under the hood, while secondary fuse panels might be inside the car, often near the dashboard or steering wheel. The fuse's wire conductor breaks when the current exceeds the ampere limit, which manufacturers usually define along with different color codes on each fuse.

Engine fuse boxes are typically situated near the battery. In this vehicle, the battery is on the driver's side, and there is a fuse box right above it with a black plastic cover to protect the fuses. On the passenger side, there is also a battery, and the fuse box is located nearby.

The most common reasons a Honda Civic won't start are a dead battery, an alternator problem, or failed starter.

There are many possible causes for a car that cranks but won't start, such as a dead battery, a faulty alternator, a bad starter, a clogged fuel filter, or a problem with the ignition system.

Which Fuse Controls the Dashboard Gauge? The instrument cluster fuse manages the dashboard gauge of a vehicle. It uses electricity from the car battery to power various electronic components of the dashboard such as the different warning lights, gauges, and alarm systems.

Usually, it will be in your garage or your basem*nt. Open the fuse box and look at the glass containers that hold the fuses. If you can see that the fuse is visibly broken, or there is metallic residue on the glass from the fuse blowing, you will need to replace that particular fuse.

You can usually find the fuse box under the hood or in the cabin of your car. Once you've found it, look at the fuse diagram and see which fuses are labeled Instrument Panel or Dashboard. Once you know which one is blown, replace it with one that has a similar amperage rating.

One possible reason why your car won't start no crank is that the fuse for the ignition switch is blown. You can check the fuse by locating it in the fuse box and inspecting it for any damage or breakage. If the fuse is faulty, you will need to replace it with a new one.

What fuses turn on with ignition? ›

A switched fuse is one that only has power when the ignition is turned on, while a constant fuse always has power.

A blown fuse in the starter circuit could be the cause of a no-start problem. Broken or corroded wiring – Damaged or dirty wires to the battery or to the starter solenoid (or wires that are loose) can prevent sufficient power from reaching the 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.

If your vehicle won't start but you hear a rapid clicking sound when you turn the key then you may have a problem with your battery or alternator.

One of the most obvious signs of a broken starter motor is when the engine cranks slowly or doesn't start at all. When you turn the key or press the start button, a healthy starter motor will engage and rapidly spin the engine.

When a car will not start, the first thing to check is the car battery. It may be simply the battery cable is corroded, sometimes re-tightening or cleaning the cables will provide enough power to start. If the cables appear okay, the battery may be at the end of its useful life.
