Perhaps the engine is not cranking at all, potentially it is turning over partially but then not starting, or maybe it’s making a clicking sound when you attempt to start the engine, but in the end absolutely nothing happens. Each of these scenarios can point to various problems with your car.

Common Reasons Why Your Nissan Moco Won’t Start

There are many reasons a Moco refuses to start. These concerns usually include a dead or weak Van battery, a bad alternator, starter motor failures, fuel system issues, along with electrical or circuitry problems.

Symptoms of Nissan Moco That Won’t Start

Having the ability to recognize and diagnose these symptoms, will assist you in finding the root cause of the issue.

Analysis of The Reasons Why Your Nissan Moco Won’t Start

The very first step to finding a practical solution to the issue is getting to grips with the root cause of that issue, so let’s explore the most typical reasons your Moco won’t start.

Nissan Moco Battery Issues

In the vast majority of cases, the most common reason why your Nissan Moco won’t start is often because of the battery, it’s either dead or weak, and you need to either recharge the battery or replace it. The vehicle’s battery supplies the power required to start the engine, and power all the electrical components in your Nissan Moco. Symptoms of a bad battery problem in a Moco, are things like the Van being slow to crank the engine, poorly lit headlights, or a lit-up battery alert light on the dashboard. 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.

Nissan Moco Alternator Problems

The alternator is responsible for charging the battery from the engine while the vehicle is running. A damaged alternator can easily prevent your Nissan Moco from starting as it will not be able to charge the battery, from the engine, so it will deplete all the way down until it’s totally dead and you don’t realize it until you get in your Moco and it won’t start. Symptoms that the alternator may be faulty can be a lit-up battery or alternator caution 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.

Nissan Moco Starter Motor Failures

The starter motor handles turning the engine over (cranking) when you start up your Nissan. If the starter motor is faulty in some way then the engine is not going to crank, and your Moco won’t start. You can tell if your starter motor has a problem or not usually by listening, if you hear a clicking noise when you turn the key in the ignition or a grinding noise throughout the start-up, or your Van only starts intermittently then the starter motor may very well be the problem.

Nissan Moco Fuel System Complications

We’re not talking about when you merely run out of gas here, but your Van’s fuel system itself having problems. Your Nissan Moco uses a combustion engine, and because of this to start and run, it needs a combination of both fuel and air. If your Moco issues are part of a faulty fuel system, this could be a clogged fuel filter or a failing fuel pump relay, which could mean the engine might not be getting the fuel it needs to get the Van 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.

Nissan Moco Electrical System or Wiring Problems

Today’s modern Nissan Mocos rely greatly on electronics, which can mean there are lots of things that can potentially have an issue. Even in an older vehicle, you can still have regular problems such as blown fuses, spark plug problems, a faulty ignition switch, or a damaged sensor, and more. These can be a few of the various electrical reasons why your vehicle will not get started. Symptoms of a circuitry or electrical issue can differ vastly however can often include the engine not cranking, or your Moco can start but just intermittently or numerous warning lights show on the dash.

How to Troubleshoot and Fix Battery Issues in a Nissan Moco

Troubleshoot and Fix Nissan Battery Issues

If it’s a battery issue you suspect is the cause of your troubles, 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 corroded you can try 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:

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 vehicle, it will probably run out of life once 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 Nissan model by visiting Amazon here, and selecting “enter a new vehicle” to filter the results for your Nissan Moco, and choose a suitable one, from a seller with great reviews.

If charging your Moco’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.

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 you’re thinking that the alternator is the cause of your Van starting troubles, you can test it. If you can get the Van to start up temporarily (you may need to jump-start the vehicle for that), but once it’s going, let the vehicle run, and while it’s running, disconnect the positive terminal of the battery. If you discover your Nissan Moco is dying immediately, then it’s most likely due to an issue with your Van’s alternator. However, be warned this test can be risky and dangerous if you don’t know what you’re doing, and may harm the sensitive electronic components in your vehicle, so its best to talk to a reliable 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.

Preventive Steps

As my dad always said “Prevention is better than cure”, so here are the best ways to ensure you can avoid any Nissan Moco starting problems ever again!

Regular Maintenance of Your Nissan Moco:

Regular Nissan Maintenance at Home

Regular maintenance of your Nissan Moco is of the utmost importance to avoiding future troubles. This consists of things like regular oil changes, checking the battery, cleaning up the terminals, changing the fuel filter as recommended/needed, and of course having your Van examined by a professional auto mechanic regularly. If you are uncertain about regular maintenance tasks needed for your particular automobile, you can consult a mechanic locally or online.

Drive Your Nissan Moco Frequently:

Drive your Nissan Regularly

If you happen to leave your Nissan Moco off for extended periods of time without driving it, the battery will waste out of charge as it’s not receiving any electrical charge from the engine running running regularly. Try to drive your Moco regularly to keep the battery full of juice. Take it for a quick spin to make sure there is still charge in the battery if you remember you have not driven your Nissan for a while. Worth noting: letting the battery fully drain, is also damaging to the longevity of the battery, try not to do this.

Pay Attention to Warning Signs:

Nissan Warning Lights on Dash

If you notice anything strange like unusual sounds, changes in how it drives and the performance, or alert lights are now visible on the dash, don’t just disregard them and get on with your day. These are usually early warning signs of a problem and it’s best to be resolved ASAP before they become larger issues later. Speak with a mechanic in your area or online about these warning symbols and find out if they need to be resolved.

When to Ask a Nissan Mechanic Online

If you’re either short on time, want a professional Nissan mechanic on hand to guide and to advise you, or you’ve attempted to resolve it yourself, but regardless of your best efforts your vehicle fails to start, then chatting with a Nissan mechanic online can be a terrific choice. It certainly beats googling things like “my Nissan wont start when its cold” all day and still getting nowhere.
