Understanding the Problem

Car Won't Start?

Before we get stuck into the causes and solutions it's important to initially understand the issue. When you hop into your car and realize “my Bentley won't start”, this could be due to an array of issues being wrong with your car. Perhaps the engine is not firing up at all, possibly it is turning over partially but then not starting, or maybe it's making a clicking noise when you try to start the engine, however, ultimately absolutely nothing happens. Each of these circumstances can be a sign of various problems with your car.

Common Reasons Why Your Bentley Won't Start

There are many reasons a Bentley won't start. These issues usually consist of a dead or weak car battery, a bad alternator, starter motor failures, fuel system issues, along with electrical or circuitry failures. Every one of these issues can manifest as an array of symptoms and require different solutions to detect and repair, so we can get your car back on the road ASAP.

Symptoms of a Bentley That Won't Start

Having the ability to recognize and diagnose these signs, will help you in discovering the underlying cause of the problem. For example, when you turn the key in the ignition, and you hear a clicking noise but your car still won't start, it can mean that there is a problem with the fuel or ignition system.

Analysis of The Reasons Why Your Bentley Won't Start

The initial step to finding a solution to the issue is knowing the underlying cause of that problem, so let's look into the most common causes as to why your Bentley won't start.

Bentley Battery Issues

In the majority of instances, the most common reason why your Bentley can't start is, in many cases down to a bad battery, it's either dead or weak, and you need to either recharge your car’s battery or replace it. The vehicle's battery stores the power needed to start the engine, and power all the electrical components in your Bentley. Signs of a bad battery problem in a Bentley can be things like the car being slow to crank the engine, dim or weak headlights, or a lit-up battery alert light on the dashboard

Bentley Alternator Problems

is my alternator stopping my car from starting?

The alternator is for charging the battery from the engine while the vehicle is running. A faulty alternator can easily prevent your Bentley from starting as it will not have the ability to charge up the battery, from the engine, so it will be drained fairly quickly until it's completely drained and you don't realize it until you get into your beloved Bentley and it refuses to start. Signs that your Bentley's alternator may be 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 sound from the engine while it's running.

Bentley Starter Motor Failures

The starter motor turns the engine over (cranking) when you start up your Bentley. If the starter motor is faulty in some way then the engine may not crank, and your Bentley can't start. You can find out if your starter motor has a problem or not typically by listening, if you hear a clicking noise when you turn your key or a grinding sound during the startup, or your car starts up but only intermittently, then the starter motor may very well be the problem.

Bentley Fuel System Complications

We’re not talking about when you just run out of gas here, but your car’s fuel system itself having complications. Your Bentley uses a combustion engine, and because of this to start and run, it needs a combination of both fuel and air. If your Bentley problems are part of a faulty fuel system, this can sometimes be a clogged fuel filter or a broken fuel pump relay, which could suggest the engine might not be getting the fuel it requires to get the car started.

Bentley Electrical System or Wiring Problems

can electrics be a reason a car wont start

Modern Bentleys rely heavily on electronic components, which can mean there are lots of things that can potentially go wrong. Even in an older model, you can have fairly normal problems such as blown fuses, spark plug problems, a broken ignition switch, a faulty sensor, and more. These can be some of the various electrical examples of how failing electrical components can be the reason your Bentley won't get started. Signs of a circuitry or electrical issue can vary greatly but can typically include the engine not cranking, your Bentley can start but only intermittently, or various alert lights showing on the car’s dash. To appropriately identify and repair these kinds of issues, you will require the abilities of a skilled car mechanic in your area or online.

Solutions & Repair Tips

When you have figured out what the cause of your Bentley being unable to start is. The next logical step is naturally to attempt to fix it. Here are some tips for the typical problems we've covered so far.

How to Troubleshoot and Fix Battery Issues in a Bentley

If you suspect it's possible a battery issue is a reason why your Bentley has trouble starting, then the first thing you should do is inspect the battery terminals. You want them to be clean, not corroded, and firmly connected. If you find that the terminals are indeed corroded you can try to clean them up with a mix of baking soda and water. You will need to replace the battery if it's weak or old, otherwise even if you charge it up enough to start the vehicle, it will probably deplete quickly again in the not-so-distant future. You can use a multimeter as a way to test the life of the battery to find out if it’s worth saving or if it needs to be changed for a new one. You can ask a reliable car mechanic online or in your area to provide guidance on this.

How to Diagnose Alternator Problems in a Bentley

If you’re thinking that the alternator is the cause of your car's starting problems, you can test it to see for yourself. If you can get the vehicle started temporarily (you may need to jump-start the car for that), but once it’s going, let the car run, and while it's running, disconnect the positive terminal of your car's battery. If you discover your Bentley dies immediately, then it's probably because of an issue with your car's alternator. You should be aware however that this method can be risky and dangerous, and might harm the sensitive electronic parts in your Bentley, so it's always best to consult with an experienced car mechanic in your area or online, before ever trying this.

How to Identify Starter Motor Failures in a  Bentley

Listen for a clicking noise when you turn the key in the ignition or press the start button if you think the starter motor is the root cause of your Bentley not starting. In these cases, the solution is to have the starter motor replaced by a professional mechanic.

How to Resolve Fuel System Problems in a Bentley

If you suspect 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 car. You should hear a humming sound for a few seconds. It might be there is an issue with the fuel pump if you are unable to hear this noise. If you observe your Bentley is difficult to start, it stalls, or it has bad acceleration, it could be due to a clogged fuel filter. Both of these will likely require a reliable car mechanic in order to correctly fix.

How to Repair Electrical or Wiring Problems in a Bentley

If you think it's a circuitry or electrical system issue, first check the fuses related to the ignition system, and change any that have actually blown. If your Bentley starts after this, then it was a successful, inexpensive, and easy fix! However, if the car does not start, even intermittently it might be an issue with the ignition switch itself. It could be a faulty sensing unit if various warning lights are lit up on the dash. These problems can be very complex and a reliable car mechanic is most likely required to identify and repair it.

Preventive Steps

As my father always stated “Prevention is better than cure”, so here are some preventative measures to make sure you can avoid any Bentley starting problems ever again!

Regular Upkeep of Your Bentley:

Regular maintenance on car to prevent starting issues

Regular upkeep of your Bentley is key to preventing future problems. This consists of things like regular oil changes, inspecting the battery, cleaning up the terminals, replacing the fuel filter as recommended/required, and of course having your vehicle examined by a professional car mechanic regularly. You can seek advice from a mechanic locally or online if you are unsure or confused about the routine upkeep jobs needed for your particular vehicle.

Drive Your Bentley Frequently:

If you happen to leave your Bentley stagnant for extended periods of time without taking it for a spin now and again, the battery will deplete as it's not getting any charge from the engine running regularly. Try to drive your Bentley frequently to keep the battery full of juice. Take it for a fast spin to make sure there is still a charge in the battery if you remember you haven't driven your Bentley for a while. Worth noting: letting the battery completely drain, is also damaging to the long-term life of the battery, try not to do this.

Pay Attention to Warning Signs:

Check Engine Control Light on a Vehicle Dashboard

If you notice anything strange like uncommon sounds, a difference in driving and performance, or alert lights lit up on your Bentley's dashboard, do not disregard them. These can be early signs of an issue and it’s best to be addressed ASAP before they become much bigger problems later. Speak with a car mechanic in your area or online about these issues and find out if they need to be addressed.

When to Ask a Bentley Mechanic Online

If you're either limited on time, want a specialist Bentley mechanic on hand to guide and advise you, or you have attempted to resolve it yourself, however regardless of your best efforts your Bentley won't start, then talking with a Bentley mechanic online can be a great option.
