Why Your Chrysler 300 2013 Cranks and Lights Up but Wont Start
There is nothing more annoying than turning your key, hearing the engine crank strong, seeing all the lights come on, and then… nothing. Your Chrysler 300 2013 cranks and lights up but wont start, and you are left standing in the driveway wondering what went wrong. This situation happens more often than you might think, and the good news is that most causes are fixable without breaking the bank.
When your car cranks normally but refuses to fire up, it means the starter motor and battery are doing their jobs. The problem lives somewhere else in the system. It could be fuel, spark, sensors, or even the security system playing tricks on you. Let us walk through each possibility step by step.
If you have ever experienced a car cranks but wont start situation before, you know the panic that sets in. The good news? You are in the right place. This article breaks down every common reason this happens on a 2013 Chrysler 300 and gives you real solutions you can use today.
Understanding What “Cranks but Wont Start” Really Means
First, let us clear up what is actually happening. When your car cranks, the starter motor is spinning the engine. When the lights turn on, your battery has power. So your car has two of the three things it needs to run. What is missing?
A running engine needs three things:
- Fuel to mix with air
- Spark to ignite the mixture
- Compression to make the combustion work
When your Chrysler 300 cranks and lights up but wont start, one of these three elements is missing or not working correctly. The trick is figuring out which one. That is exactly what we will cover next.
Top Causes of No-Start on a Chrysler 300 2013
Let us get into the specific reasons your 2013 Chrysler 300 might crank and show power but refuse to start. Each cause below is common, and each has a clear path to diagnosis and repair.
1. Fuel Pump Failure
The fuel pump delivers gas from the tank to your engine. When it fails, your engine gets no fuel. You will hear the engine crank strongly, the lights will work perfectly, but the engine will simply not fire.
Signs your fuel pump might be the culprit:
- Engine cranks for a long time before dying
- Car starts after sitting for a while but dies again quickly
- You hear a faint humming sound from the rear of the car when you turn the key to “on”
- The car stalls under heavy load or at highway speeds
On the Chrysler 300 2013, the fuel pump is a known weak point. Replacing it typically costs between $400 and $800 depending on your local labor rates. You can test the fuel pressure yourself with a fuel pressure gauge, or have a helper listen for the pump humming when you cycle the key to the “on” position (not cranking).
2. Crankshaft Position Sensor Failure
The crankshaft position sensor tells your engine computer when to fire the spark plugs. When this sensor goes bad, your engine cranks but has no idea where the pistons are. No position data means no spark, and no spark means no start.
This is one of the most common reasons a Chrysler 300 2013 cranks and lights up but wont start. The sensor is relatively cheap, usually under $50 for the part, and the labor is straightforward.
Watch for these warning signs before it completely fails:
- Intermittent stalling, especially at idle
- Rough acceleration
- Check engine light flickering on and off
- Engine dying while driving and then restarting after a few minutes
3. Ignition System Problems
Your ignition system creates the spark that ignites the fuel. When something in this system fails, you get cranking with no combustion. The most common ignition-related failures on a 2013 Chrysler 300 include worn spark plugs, faulty ignition coils, or a damaged ignition module.
Spark plugs wear out over time and need regular replacement. If you have not changed yours in 60,000 miles or more, they could be causing your no-start issue. Ignition coils are slightly more expensive but can also fail and prevent your engine from firing.
Here is a quick way to check for spark:
- Remove a spark plug wire or coil pack
- Insert a spark plug into the boot
- Ground the plug against the engine block
- Have someone crank the engine
- Look for a bright blue spark
No spark? You have found your problem. Replace the coil or spark plugs and try again.
4. Security System Lockout
Modern cars have sophisticated security systems that can prevent your engine from starting if they detect an unauthorized key or a system fault. The Chrysler 300 uses a PASS-Key security system, and sometimes it gets confused.
If your security light stays on or flashes when you turn the key, the system might be blocking the engine from starting. This is often caused by a worn key transponder, a faulty lock cylinder, or a problem with the body control module.
Try these steps first:
- Try a spare key if you have one
- Wait 10 minutes with the key in the “on” position to see if the security light stops flashing
- Check that the key battery is fresh (if using a remote key)
If the security system is locking you out, you may need a dealer or locksmith to reprogram or replace the key. Sometimes a simple key-related fix can resolve the issue without major repairs.
5. Clogged Fuel Filter or Injectors
Even if your fuel pump is working, fuel needs to reach the engine cleanly. A clogged fuel filter or dirty fuel injectors can starve your engine of fuel, causing it to crank but not start.
Fuel filters on the Chrysler 300 are located along the fuel line and should be replaced every 30,000 to 60,000 miles. If you have never changed yours, this could be contributing to your no-start problem. Similarly, dirty injectors can restrict fuel flow enough to prevent startup, especially in cold weather.
How to Diagnose the Problem at Home
You do not need to be a professional mechanic to narrow down the cause. With a few basic tools and some patience, you can figure out whether your problem is fuel, spark, or security related.
Step 1: Check for Spark
Remove a spark plug and ground it against the engine. Have someone crank the engine. If you see spark, your ignition system is working. If not, focus on the ignition coils and crank sensor.
Step 2: Check for Fuel
Listen for the fuel pump hum when you turn the key to “on.” You can also spray a small amount of starting fluid into the throttle body. If the engine fires briefly and then dies, your problem is fuel delivery. A faulty oil sensor can sometimes throw off your diagnosis, so always check multiple systems.
Step 3: Check for Security Light
Look at your dashboard when you turn the key. If the security or theft light stays on solid or flashes rapidly, the security system is likely involved.
Step 4: Scan for Error Codes
An OBD-II scanner is a worthwhile investment for any car owner. Plug it into your Chrysler 300 and read the codes. Common codes for a no-start condition include P0335 (crankshaft position sensor), P0230 (fuel pump primary circuit), and U0100 (lost communication with ECM).
When to Call a Professional Mechanic
Some repairs are simple enough for a DIY enthusiast. But certain Chrysler 300 2013 no-start issues really do need a professional touch. Here are the situations where you should call in the experts:
- Internal engine damage such as a broken timing chain or seized engine
- Wiring harness issues deep inside the engine compartment
- Body control module failure that requires specialized programming
- Fuel system problems that require dropping the tank and replacing the pump
- When you have checked all the basics and still cannot find the cause
A qualified mechanic will have access to advanced diagnostic tools that can read live data from your sensors. This speeds up the diagnosis significantly. If your car cranks and lights up but wont start, and you have already checked the fuel pump, spark, and security system, it is time to book a professional appointment.
Also, if you are dealing with a situation where your engine cranks but will not start and you suspect the issue is related to oil or engine lubrication, remember that running a car without proper oil can cause serious internal damage. A car without oil may still crank, but the engine could be suffering from internal wear that prevents it from starting properly.
Prevention Tips to Avoid Future No-Start Issues
The best way to deal with a no-start problem is to prevent one from happening in the first place. Here are simple habits that keep your Chrysler 300 2013 running strong:
- Change your fuel filter every 30,000 to 60,000 miles
- Replace spark plugs on schedule, typically every 30,000 to 60,000 miles
- Use quality fuel from reputable stations to keep injectors clean
- Keep your battery terminals clean and tight
- Address warning signs early like stalling, rough idle, or difficulty starting
- Have a professional scan your computer system at least once a year
These small maintenance steps add up to a lot of peace of mind. Your Chrysler 300 is a powerful and comfortable sedan, and with proper care, it will keep starting reliably for years to come.
Final Thoughts
Dealing with a Chrysler 300 2013 cranks and lights up but wont start situation is stressful, but it is almost always fixable. The most common causes are fuel pump failure, crankshaft position sensor issues, ignition problems, or security system lockout. By working through the diagnostic steps in this guide, you can narrow down the problem and either fix it yourself or give your mechanic the information they need to solve it quickly.
Do not ignore the problem. A no-start condition will not fix itself, and the longer you wait, the more damage can occur. Start with the simple checks, work your way through the list, and you will likely find the answer. If you have tried everything and still cannot get your car running, reach out to a trusted mechanic who specializes in Chrysler vehicles.
Remember, your car has power, the engine turns over, and the lights work. That means the foundation is strong. You just need to find the missing piece of the puzzle. With the right information and a little patience, you will be back on the road in no time.
Frequently Asked Questions
Why does my Chrysler 300 2013 crank but not start when the battery is good?
A good battery means the starter and electrical systems are working, so the problem lies elsewhere. The most common causes are a failed fuel pump, a bad crankshaft position sensor, or an ignition system fault. You should check for spark and fuel delivery first before replacing expensive parts.
Can a bad crankshaft position sensor cause a Chrysler 300 to crank but not start?
Yes, absolutely. The crankshaft position sensor tells the engine computer when to fire the spark plugs. Without this signal, the engine cranks normally but never ignites the fuel. Replacing this sensor is one of the most common fixes for this exact problem on the 2013 Chrysler 300.
How do I know if my fuel pump is bad in a 2013 Chrysler 300?
Signs of a failing fuel pump include a long cranking time before starting, stalling under load, and a complete no-start condition with full electrical power. You can test it by listening for the pump hum when you turn the key to “on,” or by checking fuel pressure with a gauge.
Is it safe to use starting fluid to diagnose a no-start Chrysler 300?
Yes, it is a safe diagnostic method. Spray a small amount of starting fluid into the throttle body while someone cranks the engine. If the engine fires briefly and then dies, your problem is fuel delivery. If it does not fire at all, the problem is likely spark or compression. Always use starting fluid sparingly and follow safety precautions.
Can the security system on a Chrysler 300 prevent the car from starting?
Yes, the PASS-Key security system on the 2013 Chrysler 300 can lock out the engine if it detects an unrecognized key or a system fault. If the security light stays on or flashes when you turn the key, this is likely the cause. Try a spare key first, and if that does not work, you may need the system reprogrammed.
How much does it cost to fix a Chrysler 300 that cranks but won’t start?
Costs vary widely depending on the cause. A crankshaft position sensor replacement typically costs $100 to $200. A fuel pump replacement runs $400 to $800. Ignition coil replacements are usually $150 to $300. Security system repairs can range from $100 for a simple reprogram to several hundred dollars for more complex issues.
