When your Dodge Dart won’t start, it’s often a common electrical or fuel system issue that can be diagnosed with a systematic approach.
Few things cause more immediate stress than a car that refuses to crank. Your Dodge Dart, a reliable companion for many, can sometimes throw a curveball. We’ll walk through the most common reasons your Dart might be acting stubborn and how to approach each one.
Initial Checks: The Basics
Before diving deep, cover the fundamental checks. These simple steps often resolve the issue quickly.
Battery Condition
A dead or weak battery is the most frequent culprit. Cold weather severely impacts battery performance.
Look for corrosion on the battery terminals. Clean any white or green buildup with a wire brush and a baking soda solution.
Ensure the battery cables are tight. Loose connections prevent proper power flow.
Try a jump start. If the Dart starts and runs, the battery or charging system needs attention.
A multimeter can confirm battery voltage. A healthy battery should read around 12.6 volts when the engine is off.
Starter Motor Sounds
Listen carefully when you turn the key or push the start button. The sounds provide clues.
- No sound: Points to a completely dead battery, a faulty starter, or an ignition switch problem.
- Single click: Often indicates a starter solenoid failure or a severely discharged battery. The solenoid tries to engage but lacks power.
- Rapid clicking: This usually means a weak battery. There isn’t enough power to fully engage the starter motor.
Check the Gear Selector
The Dart, like most automatic vehicles, must be in Park (P) or Neutral (N) to start. This is a safety feature.
Wiggle the shifter firmly into Park. Try starting it. If it still won’t start, try Neutral.
A faulty neutral safety switch can prevent starting even when the shifter is correctly positioned.
Fuses and Relays
The fuse box protects electrical components. A blown fuse can stop your Dart from starting.
Locate the fuse boxes. Your Dart has one under the hood and another inside the cabin.
Consult your owner’s manual for fuse box diagrams. Look for fuses related to the starter, ignition, and fuel pump.
The starter relay is also a common failure point. Swapping it with a known good, identical relay (like the horn relay) can help diagnose it.
Dodge Dart Not Starting: Electrical System Deep Dive
If the basics don’t pan out, it’s time to dig deeper into the electrical system. This network powers everything.
Battery Load Test and Charging System
A battery can show good voltage but fail under load. Auto parts stores often offer free battery load tests.
The alternator recharges the battery while the engine runs. A failing alternator means the battery won’t stay charged.
Check the alternator belt for proper tension and wear. A loose or broken belt prevents the alternator from spinning.
Starter Motor and Solenoid
The starter motor is a small electric motor that cranks the engine. The solenoid acts as a switch, engaging the starter gear.
A failing starter motor might only click or make grinding noises. It might also draw too much current, draining the battery rapidly.
Testing the starter often involves checking voltage at its main terminal and the solenoid wire during cranking.
Ignition Switch Assembly
The ignition switch sends power to various circuits when you turn the key. Wear and tear can affect its internal contacts.
Symptoms of a bad ignition switch include no power to accessories, no crank, or intermittent starting issues.
Replacement involves careful removal of steering column covers and electrical connectors.
Wiring and Ground Connections
Corroded or loose ground wires can disrupt electrical flow. The engine needs a solid ground connection to the chassis and battery.
Inspect the main battery cables. Look for fraying, corrosion, or damage along their length.
Pay attention to the main engine ground strap. It connects the engine block to the vehicle’s frame.
| Symptom | Primary Culprit | Secondary Culprit |
|---|---|---|
| No crank, no sound | Dead Battery | Ignition Switch |
| Single click | Starter Solenoid | Very Low Battery |
| Rapid clicking | Weak Battery | Loose Battery Cables |
| Cranks, no start | Fuel Pump | Ignition Coils |
Fuel Delivery System Troubles
Even with perfect electrical power, your Dart needs fuel to run. Issues here are common.
Fuel Level and Gauge Accuracy
It sounds simple, but confirm you have enough fuel. Fuel gauges can sometimes be inaccurate.
Try adding a gallon or two of fresh fuel. This eliminates “running out” as a possibility.
Fuel Pump Failure
The fuel pump pushes fuel from the tank to the engine. It’s often located inside the fuel tank.
Listen for a faint hum from the rear of the car when you turn the key to the “on” position (before cranking). This indicates the pump is priming.
A clogged fuel filter can also restrict fuel flow, mimicking a weak pump. The fuel filter is usually in-line or part of the pump assembly.
Testing fuel pressure at the fuel rail confirms proper pump operation. This requires a specialized gauge.
Fuel Pump Relay and Fuse
The fuel pump relies on a relay and a fuse. These components provide power to the pump.
Check the fuel pump fuse in the under-hood fuse box. A blown fuse means no power to the pump.
The fuel pump relay can fail electrically. Swapping it with another identical relay can help identify a fault.
Fuel Injectors
Dirty or faulty fuel injectors prevent fuel from entering the engine’s cylinders. The engine will crank but not start.
Modern engines rely on precise fuel injector operation. Diagnostics can often pinpoint a specific faulty injector.
Ignition System and Engine Mechanical Issues
Once fuel and power are confirmed, the ignition system provides the spark. Mechanical problems are rarer but severe.
Spark Plugs and Ignition Coils
Spark plugs ignite the fuel-air mixture. Worn or fouled plugs prevent proper combustion.
Each cylinder has an ignition coil. A faulty coil won’t produce spark for its cylinder.
Checking for spark involves removing a plug or coil and using a spark tester. This should be done carefully.
Crankshaft and Camshaft Position Sensors
These sensors tell the engine computer (PCM) the exact position of the crankshaft and camshafts. This timing is critical for spark and fuel delivery.
A failing Crankshaft Position Sensor (CKP) is a very common no-start cause. The engine cranks but gets no spark or fuel injection.
A failing Camshaft Position Sensor (CMP) can also cause a no-start, often with longer crank times.
These sensors are usually relatively inexpensive but can be tricky to replace depending on their location.
Engine Timing and Compression
A broken timing belt or chain is a catastrophic mechanical failure. This prevents the engine from running.
Loss of engine compression means the cylinders cannot properly compress the fuel-air mixture. This can result from worn piston rings or damaged valves.
A compression test measures the pressure within each cylinder. This requires specialized tools and expertise.
| Tool | Purpose |
|---|---|
| Multimeter | Checking battery voltage, continuity, resistance. |
| Jumper Cables | Attempting a jump start. |
| Test Light | Checking for power and ground at various circuits. |
| Fuel Pressure Gauge | Measuring fuel system pressure. |
| OBD-II Scanner | Reading diagnostic trouble codes (DTCs). |
Security System Glitches
Modern vehicles, including your Dart, have sophisticated anti-theft systems. These can prevent starting if a problem arises.
Immobilizer System
The immobilizer uses a chip in your key to communicate with the car’s computer. If the chip isn’t recognized, the engine won’t start.
Try a different key if you have one. A damaged key chip can be the issue.
A weak key fob battery might also interfere with the immobilizer’s communication. Replace the fob battery.
Anti-Theft System Engagement
If the anti-theft system senses a threat, it can disable the starter or fuel system. Look for a security light flashing on the dashboard.
Sometimes, a “relearn” procedure can reset the system. This often involves specific key turns or door lock sequences outlined in your owner’s manual.
A failing Body Control Module (BCM) or Powertrain Control Module (PCM) can also cause security system issues, preventing the car from starting.
These modules are the brains of the car. Their failure often requires professional diagnostic tools and programming.
Dodge Dart Not Starting — FAQs
Why does my Dodge Dart click but not start?
A clicking sound, especially rapid clicking, usually points to a weak or dead battery. There isn’t enough power to fully engage the starter motor. A single click often means the starter solenoid is failing or the battery is severely discharged.
Can a bad fuel pump prevent my Dodge Dart from starting?
Absolutely. If the fuel pump isn’t delivering fuel to the engine, it won’t start, even if it cranks perfectly. You might hear the engine crank normally but never catch or fire up. Listen for a faint hum from the rear when you turn the key to the “on” position.
