Why Won’t My a Mercedes Start?

Before we dive into the list of possible faults and fixes, it’s key to first get on the same page of the central issue. When you hop in your Mercedes Citan and realize “it won’t start!”, there could be several parts causing the headaches. Maybe the engine isn’t cranking at all, or maybe it’s cranking but not firing. Or you might notice clicking sounds when you try to start it, but sadly no ignition occurs. Each scenario can indicate different mechanical issues.

Common Reasons Why Your Mercedes Citan Won’t Start

There are many contributing factors why your Citan won’t start up. The usual suspects include a weak or drained battery, faulty alternator, starter motor complications, fuel system snags, plus electrical or wiring issues. Every one of these concerns can present differently, requiring specific methods of troubleshooting and fixing to get you back on the open road ASAP. All of which, we’ll delve into.

Symptoms of a Mercedes Citan That Won’t Start

Identifying these symptoms will lead you to the core mechanical problem. For instance, when you turn the key and you hear it turning over yet no start up, it often indicates a fuel or ignition issue.

Analysis of The Reasons Why Your Mercedes Citan Won’t Start

The initial move in fixing the no-start nuisance is pinpointing the precise cause of the problem. So let’s take a closer look at the most common explanations for the Citan not starting when you turn the key.

Battery Issues in a Mercedes Citan

In the vast majority of situations, the most common reason a Mercedes Citan won’t start comes down to issues with the battery. Specifically, a weak or dead battery prevents the engine from turning over. The car’s battery supplies the necessary electrical juice to start the engine and energize all your electronics. Signals of a struggling battery entail labored or difficult cranking, dim headlights, or a battery alert symbol illuminated on the dash. A battery charger can recharge a drained battery if you don’t have the help of another vehicle to jump start it, but do have an electrical socket nearby like at home.  And a portable jump starter lets you charge p the battery without another vehicle, and by the roadside without the need for an electrical socket, so you are never stuck.

Alternator Problems in a Mercedes Citan

The Alternator keeps the battery charged by using engine power while driving. A malfunctioning alternator can easily stop your Mercedes Citan from starting since it fails to recharge the battery, depleting it fully so that one day you climb into your ride and it simply can’t start. Clues of a problematic alternator may include an illuminated battery or alternator caution light on the dash, dull headlights while idling, or a grinding noise from the engine while running.

Starter Motor Failures in a Mercedes Citan

The starter motor is key to turning the engine when you turn the key to start your Mercedes. If the starter is faulty, the engine can’t crank, keeping your Citan from starting. Listen out for clicking sounds when you turn the key or grinding as you try to start it, which could indicate starter problems.

Fuel System Issues in a Mercedes Citan

We’re not talking about running out of gas like a silly goose. Instead, it’s problems in the fuel system itself potentially leaving your Citan unable to start up. Your car uses gas uses gas to mix with air and runs the engine. So problems here like a clogged fuel filter or damaged fuel pump relay can result in the engine is unable to get the fuel it requires for ignition. Fuel injectors can also get clogged over time, so consider a fuel injector cleaner like Red Line to clean them out and improve starting.

Electrical System or Wiring Problems in a Mercedes Citan

Ok, well yes that image is a joke, but I want to emphasize modern cars now rely heavily on electronics, expanding what can go wrong. With older models, the usual suspects include blown fuses, spark issues, faulty ignition switches, or broken sensors. Electrical issues and electronics like these may prevent your Mercedes Citan from starting. Watch for your car only starting sometimes, dashboard alerts, or failure to crank as signs of an underlying electrical issue. Pinpointing and fixing these often needs a certified mechanic near you.

Solutions: Let’s Get Your Mercedes Citan Starting Again!

If you think you might know what the issue may be, it’s time to figure out the reason behind your car’s failure to start, and then the logical next move is to try to mend the problem. Here’s advice for the common problems we’ve discussed up to this point:

How to Identify and Fix Battery Issues in a Mercedes Citan

car not starting but battery is fine

The first step if a battery issue is suspected for the no start is to inspect the battery terminals. Verify they are clean, tight, and properly connected. If the terminals are in fact dirty, try scrubbing them with a sodium bicarbonate(baking soda) and water solution.

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 fully and performs as expected, the issue may be resolved. However, replacing the battery will be required if it is aged, dead or lacks capacity. Otherwise, even sufficiently charging it to start your Citan may only provide temporary relief before it likely runs out of power again soon. Using a multimeter or OB2 scanner to evaluate the battery’s condition can determine if it’s worth preserving or requires swapping out. Suitable replacement batteries for your specific Mercedes can be found on Amazon here by entering your vehicle details to filter for the right fit and choosing a highly-rated seller.

If charging your Citan’s battery fails to solve ongoing issues like frequent draining and recharging even after installing a new battery, an underlying problem likely causes the excessive drain. Professional diagnostic services would then be needed to inspect and identify the root cause. You can also consult a mechanic online through us or obtain an instant quote from a mobile mechanic.

How to Identify and Fix Alternator Problems in a Mercedes Citan

Car wont start replace alternator needed

If you think the alternator is the reason your Mercedes Citan won’t start, a test can confirm. If you can temporarily get the car running (you may need a jump start), and while it’s running, disconnect the positive terminal of your car’s battery. If the vehicle dies pretty quickly after that, it’s likely a bad alternator. However, be careful this test can be risky and mess up delicate electronics in your ride, so consulting a trained mechanic locally or online is best prior to trying it.

If you figure out that the alternator is the problem, it’s a case of having it replaced. I recommend consulting an online or local mechanic as they will advise you on how difficult the repair is for your specific model, and you can work out if you want to try it yourself, or with the advice of an online mechanic

If you do want to try it yourself or take it to a local garage, you can often buy the replacement parts yourself cheaper than at the garage, but you need to know what to get for your model of Mercedes Citan. You find all the information you need about your specific vehicle by searching online for something like “free vin check Mercedes“, which is a purchasable report, that will give the specs for your vehicle and which parts are compatible, and then you can go get the alternator parts you need. However, an easier option is, Amazon probably has the alternator you need online, at a cheaper price, and their site easily shows which ones will go in your specific car model. Check the Amazon alternator page here

How to Identify and Fix Starter Motor Problems in a Mercedes Citan

If you believe the starter motor might be causing your Mercedes Citan to not fire up, pay attention for a clicking noise when you try and start it. If present, but the engine does not turn over, the starter motor likely requires replacing. You can take it to a local garage and have them repair it, or repair it yourself with the help and advice from an online mechanic guiding you. 

If you need it, one of the cheapest and easiest places to get a new starter motor, for your exact vehicle model is on the Amazon here.

How to Identify and Solve Fuel System Problems in a Mercedes Citan

If you think a fuel system issue might be to blame for the no-start, tune your ears for the fuel pump hum when you flip the key to “on” before trying to turn over the car. The pump should make a faint humming for a few seconds. If such a noise is not heard, the fuel pump could be defective. Difficult starting, stalling, or lagging acceleration may also stem from a problematic or clogged fuel filter. Filter and pump issues normally need a skilled mechanic to diagnose and fix them properly, often using fuel pressure testing and precise diagnostic equipment. Later in this article, I detail the best ways to get help from a local Mercedes mechanic near you. 

How to Fix Electrical or Wiring Problems in a Mercedes Citan

If you suspect it’s an electrical circuitry problem, first inspect the fuses for the ignition system, and replace any that have blown. If your Citan starts after this, it was a successful, cheap fix! However, if it still won’t start, even sometimes, the ignition switch itself could be the cause of the issue. Warning lights on the dashboard could additionally mean a faulty sensor. These can be intricate issues needing a professional mechanic to identify and properly repair (see below advice on local mechanics).

How to Prevent Starting Issues in a Mercedes Citan

As granpa used to say: “An ounce of prevention is worth a pound of cure”. Here’s how to prevent future problems starting your Citan:

Routine Upkeep of Your Mercedes Citan

Regular maintenance on car to prevent starting issues

Routine maintenance is essential to avoiding issues, including oil changes, battery checks, cleaning terminals, replacing the fuel filter as needed, and having a mechanic check over the car regularly. If unsure about maintenance for your model, ask a mechanic locally or online for guidance.

Drive Your Citan Frequently

drive regular to avoid car troubles

If your Mercedes Citan happens to sit unmoved in your garage or driveway for extended times without being driven, the battery can reduce as it is not being recharged by the engine running, through the alternator. Try your best to drive your Mercedes Citan regularly to maintain a charged battery. If you remember you haven’t driven your car in a while, take it for a short drive around town to ensure there is still a charge left.

Note: Letting the battery fully drain is also bad for its longevity, so try to avoid that.

Pay Attention to Warning Signs

Check Engine Control Light on a Vehicle Dashboard

If you notice any irregular things like unusual noises, changes in driving and performance, or warning lights lit up on the dashboard, do not ignore them. These are often early signs of an issue that should be addressed ASAP before they escalate into larger problems later on. Consult with a mechanic locally or online about these problems and get advice on if they require attention.

When to Ask a Mercedes Mechanic Online

If you have limited time available, or despite putting in real effort on your own, you still can’t get your car to start, consider consulting a Mercedes mechanic online. It delivers expert guidance in just minutes from the comfort of your living room, and is far less expensive than a tow and diagnosis at the local garage.

Frequently Asked Questions (FAQs) When a Mercedes Citan Won’t Start

Mercedes Citan won’t start but lights come on?

If your Mercedes Citan‘s lights turn on but it still won’t start, the issue is likely not related to the battery. More than likely there is a problem with the starter motor. Investigate if you hear any clicking noises when trying to turn the key. If so, the starter motor is trying to engage but failing. Have a mechanic examine the starter motor – it may need to be repaired or replaced.

Mercedes Citan won’t start but has power?

When your Mercedes Citan has power (lights, radio etc work) but does not start up, there may be a fuel delivery problem. Issues like a faulty fuel pump relay could stop fuel getting to the engine. Without enough fuel, combustion can’t happen and the engine won’t start. Listen near the back seat when turning the key – you should hear the fuel pump prime for a few seconds. If not, get a mechanic check the fuel system.

Mercedes Citan won’t start but battery is fine?

If your Mercedes Citan‘s battery tests fine and is fully charged, but the car still refuses to start, the underlying cause is likely electrical. Potential culprits include a bad ignition switch, broken sensor, or wiring problems. As electrical issues can be tricky, diagnosis by a professional mechanic is best. They can accurately identify the specific electrical fault and have it repaired.

Mercedes Citan won’t start just clicking?

When you turn the key and there’s only a clicking noise but the engine fails to turn over, the most common cause is a faulty starter motor. The click comes from the starter solenoid attempting to activate the starter motor, but the motor itself fails to spin up the engine. As the starter motor needs mechanical repair or replacing, seek help from a reliable mechanic to get your Mercedes Citan running again.

What if my Mercedes Citan won’t start up?

First things first, take a deep breath and try to stay calm. Check for any odd noises, flashing lights, or changes in how it runs that could point to the issue. Chances are the culprit is one of the common problems we will talk about here. If you still can’t locate the exact issue, you’ll have to consult a trusted Mercedes mechanic locally or online.

Determine if my Mercedes Citan won’t start because of the battery?

Signs that your Mercedes’s battery is the issue are, a slow cranking engine, dim headlights, and battery warning symbols lighting up on the dash. Also check that the battery terminals are clean, corrosion-free, and tightly fastened. If your battery is older it’s probably best to just replace it completely.

How to prevent my Mercedes Citan from failing to start in the future?

To prevent this hassle from repeating, scheduled upkeep is crucial. This includes oil changes, inspecting the battery and cleaning its terminals, replacing the fuel filter when necessary, and getting your Mercedes Citan checked out by a mechanic frequently. Additionally, make sure to drive the car often so the battery stays charged.
