When you realize to yourself “My Honda Horizon won’t start”, this could be due to various things being wrong with your car. Possibly the engine is not firing up at all, possibly it is cranking partially however then not starting, or perhaps you can hear a clicking sound when you attempt to start the engine, however ultimately absolutely nothing happens. Each of these scenarios can point to different problems with your car.

Common Reasons Why Your Honda Horizon Won’t Start

There are numerous reasons a Horizon fails to start up. These problems usually include a dead or weak car battery, a bad alternator, starter motor issues, fuel system issues, along with electrical or wiring complications. Each one of these problems can show up as an array of symptoms and require separate solutions to troubleshoot and resolve, so we can get your car back on the road ASAP.

Symptoms of Honda Horizon That Won’t Start

Having the ability to identify and diagnose these symptoms, will assist you in finding the root cause of the issue. For example, when you turn the key in the ignition, and you hear a clicking noise but your car still fails to start, it can mean that there is a problem with the fuel or ignition system.

Analysis of The Reasons Why Your Honda Horizon Won’t Start

The initial step to discovering a practical solution to the issue is knowing the root cause of that problem, so let’s look into the most typical reasons your Horizon will not start.

Honda Horizon Battery Issues

In the vast majority of instances, the most common reason why your Honda Horizon will not start is, in many cases because of the battery, it’s either dead or weak, and you need to charge up your car’s battery or change it. The car’s battery stores the electric that’s needed to start the engine, and power all the electrical components in your Honda Horizon. Symptoms of a bad battery issue in a Horizon, are things like the vehicle being sluggish to crank the engine, dim or weak headlights, or a lit-up battery alert light on your car’s dash. A portable jump starter allows you to jump start your vehicle’s if the battery is dead without needing another vehicle. And a battery charger can help recharge a dead battery and diagnose battery issues.

Honda Horizon Alternator Problems

Faulty Alternator means car wont start

The alternator is for charging the battery from the engine while the vehicle is running. A faulty alternator can certainly stop your Honda Horizon from starting as it wont have the ability to charge the battery, from the engine, so it will be depleted fairly quickly until it’s completely drained and you only realize it when you can’t get your Honda to fire up. Symptoms that your Horizons alternator is faulty include a lit-up battery or alternator warning light on the dashboard, weak or dim headlights when the engine is idling, and also a whining or grinding noise from the engine while it’s running.

Honda Horizon Starter Motor Failures

my car wont start is the starter motor?

When you start your Honda Horizon, the starter motor is responsible for turning the engine over (cranking it). If the starter motor is failing in some way then the engine is not going to crank, and your Horizon won’t start. You can tell if your starter motor has an issue or not usually by listening for a clicking noise when you turn the key in the ignition or a grinding noise throughout the startup, or your car only starts intermittently then the starter motor may very well be the problem.

Honda Horizon Fuel System Complications

Now we’re not talking about when you merely run out of gas here, but your car’s fuel system itself having complications. Your Honda Horizon uses a combustion engine, and, therefore, to start and run, it needs a combination of both fuel and air. If your Horizon issues are because of a faulty fuel system, this might be a clogged fuel filter or a broken fuel pump relay, which could indicate the engine may not be getting the fuel it needs to get the vehicle started. Over time fuel injectors can also get clogged, so using a fuel injector cleaner like Red Line can help clean them and improve starting.

Honda Horizon Electrical System or Wiring Problems

Ok, well yes this image is a joke, but all the same, today’s modern Honda Horizons rely greatly on electronic components, which can mean there are lots of things that can potentially go wrong. Even in an older car, you can still have regular issues such as blown fuses, spark plug issues, a faulty ignition switch, or a damaged sensor, and more. These can be a few of the many electrical explanations as to why your vehicle can’t get started. Indications of a circuitry or electrical problem can vary vastly but can typically include the engine not cranking, or your Horizon can start however just intermittently or some warning lights are lit up on the dashboard. To effectively identify and fix these kinds of issues, you will require the abilities of a skilled Honda mechanic locally or online.

Solutions & Repair Tips

Once you have determined what the cause of your vehicle failing to start is. The next logical step is of course to attempt to repair it. Here are some pointers for the common problems we’ve covered up until this point.

How to Troubleshoot and Fix Battery Issues in a Honda Horizon

my car wont start i think its the battery

If you suspect it’s possibl a battery issue is the culprit as to why your Horizon has difficulty starting, then the first thing you must do is examine the battery terminals. You want them to be clean, not corroded, and securely connected. If you discover that the terminals are in fact corroded you can attempt cleaning them with a mix of baking soda and water.

Once you have checked the battery terminals, you can check to see if the battery is just out of charge, or worse, it’s old and weak, or dead and needs to be replaced. For this, you can charge the battery in a few different ways:

At Home Battery Charger - YONHAN - Fully Automatic

Jumper Cables by Energizer for Car Battery - Heavy Duty

NOCO Boost Plus GB40 1000A UltraSafe Car Battery Jump Starter

YONHAN Battery Charger Fully-Automatic

Energizer Jumper Cables for Car Battery, Heavy Duty

If the battery charges up and works fine, great, problem solved! However, if the battery is old or weak, you will have to replace it. Otherwise, even if you charge it up enough to start the Honda Horizon, it will likely run out of life again in the near future. You can use a multimeter or OB2 scanner as a way to test the life of the battery to see if it’s worth saving or if it needs to be replaced. You can get a replacement car battery for your exact Honda model by visiting Amazon here, and selecting “enter a new vehicle” to filter the results for your Honda Horizon, and choose a suitable one, from a seller with great reviews.

If charging your Horizon’s battery does not resolve your issues, and problems like frequent draining and needing frequent charges persist even after replacing the battery, there is likely a more complex underlying issue causing excessive battery drain. In that case, you will need a professional mechanic to inspect and diagnose the root cause. You can also ask the advice of a mechanic online through us, or get an instant free quote on a Emergency mechanics service near me.

How to Diagnose Alternator Problems in a Honda Horizon

Ok, so the image above I found online and is a joke, DON’T DO THIS. I’ll explain in more detail, but in short, to diagnose and fix alternator problems you will need the help of a qualified and experienced auto mechanic. If the alternator is what you think is the offender, you can test it to see for yourself. If you can get the vehicle to start up temporarily (you may need to jump-start the vehicle for that), but when it’s going, let the vehicle run, and while the engine is running, disconnect the positive terminal of the battery. It’s likely the result of a fault with your vehicle’s alternator if you notice that your Honda Horizon dies immediately when you disconnect the positive terminal. However, be warned this test can be risky and dangerous if you don’t know what you’re doing, and may harm the delicate electronic components in your vehicle, so its best to chat with an experienced mechanic locally or online, before ever trying this. If you think it might be the alternator, it’s best to ask a mechanic online or near you.

How to Identify and Solve Starter Motor Failures in a Honda Horizon Honda Starter Motor Replacement by a qualified mechanic

If you suspect the starter motor is the cause of your Honda Horizon refusing to start up, listen for a clicking noise when you turn the ignition key. In this case, the solution is to have the starter motor replaced by a professional mechanic.

How to Resolve Fuel System Complications in a Honda Horizon

If you think the issue to be due to a fuel system problem, try and listen for the fuel pump when you turn the key to the “on” position, before starting the vehicle. You should be able to hear a humming noise for a few seconds. If you are unable to hear this noise, then it may be there is cause for concern with the fuel pump. If you observe your Honda is difficult to start, it stalls, or it has poor acceleration, it could be down to a clogged fuel filter. Both of these will likely require a professional auto mechanic in order to properly repair. This is because may require a fuel pressure test kit and mechanic’s tool set to fully diagnose and repair fuel system problems.

How to Repair Electrical or Wiring Problems in a Honda Horizon

If you think it’s a circuitry or electrical system problem, first check the fuses associated with the ignition system, and replace any that have actually blown. If your Horizon starts after this, then it was an effective, simple and cheap fix! However, if the vehicle doesn’t start, even intermittently it might be an issue with the ignition switch itself. If different warning lights show up on your dashboard, it could be a damaged sensor. These issues can be very complex and a reliable Honda mechanic is most likely needed to identify and fix it. 

Preventive Steps

As my father always said “Prevention is better than cure”, so here are some preventative measures to ensure you avoid any Honda Horizon starting troubles again!

Routine Maintenance of Your Honda Horizon:

Regular maintenance of your Honda Horizon is key to avoiding future difficulties. This includes things like routine oil changes, checking the battery, cleaning the terminals, replacing the fuel filter as advised/required, and of course having your vehicle inspected by a reliable auto mechanic routinely. You can seek advice from a mechanic locally or online if you find yourself uncertain or not sure about the regular maintenance jobs required for your particular vehicle.

Drive Your Honda Horizon Frequently:

If you happen to leave your Honda Horizon off for extended periods of time without driving it, the battery may waste out of charge as it’s not being charged up by the engine being used. Try to drive your Horizon frequently to keep the battery from draining. Take it for a fast spin to make sure there is still charge in the battery if you remember you have not driven your Honda for a while. Worth noting: letting the battery totally drain, is also damaging for the long-term life of the battery, try not to do this.

Take Notice Of Warning Signs:

These are usually early warning signs of a problem and are best being resolved ASAP so that they don’t end up being much bigger issues later. Chat with a mechanic locally or online about these issues and get advice on if they need to be resolved.
