Fuel System Issues:
* Fuel pump failure: The fuel pump is responsible for delivering fuel to the engine. A failing pump can cause the engine to sputter and die.
* Fuel filter clog: A clogged fuel filter restricts fuel flow to the engine.
* Fuel pump relay failure: The relay switches power to the fuel pump. A faulty relay can prevent the pump from working.
* Empty or nearly empty fuel tank: Seems obvious, but worth mentioning!
* Bad fuel injectors: These spray fuel into the engine. Clogged or failing injectors can lead to a loss of power and stalling.
Ignition System Issues:
* Crankshaft Position Sensor (CKP) failure: This sensor tells the computer the engine's rotational speed. A faulty sensor will prevent the engine from starting or running.
* Camshaft Position Sensor (CMP) failure: Similar to the CKP sensor, but monitors the camshaft.
* Ignition coil failure: The ignition coil provides the high voltage needed to ignite the fuel-air mixture.
* Spark plugs or wires: Worn or damaged spark plugs or wires can prevent proper ignition.
* Distributor issues (if applicable): Older Sebrings might have distributors; problems there can affect ignition.
Other Potential Problems:
* Alternator failure: The alternator charges the battery. A failed alternator will drain the battery, eventually causing the engine to stall.
* Battery failure: A dead or dying battery can prevent the engine from starting or running.
* Overheating: An overheated engine can shut down to prevent damage. Check your coolant level.
* Transmission problems: While less likely to cause a complete stop, transmission issues can sometimes cause a sudden loss of power.
* Computer/ECU problems: The engine control unit (ECU) controls many engine functions. A faulty ECU can cause a variety of problems, including stalling.
* Vacuum leaks: Leaks in the vacuum system can disrupt engine operation.
Troubleshooting Steps (Proceed with caution):
1. Check the obvious: Is the fuel tank nearly empty? Are there any warning lights illuminated on the dashboard?
2. Check the battery: Test the battery voltage. A low voltage indicates a possible battery or alternator problem.
3. Try to restart the car: If it starts easily, the problem might be intermittent and require further investigation.
4. Listen for unusual noises: Any unusual clicking, grinding, or whirring sounds could indicate a specific component failure.
Next Steps:
Because there are so many possibilities, it's strongly recommended that you have a qualified mechanic diagnose the problem. Trying to troubleshoot complex engine issues yourself can be dangerous and potentially lead to further damage. They have the tools and expertise to pinpoint the exact cause and perform the necessary repairs.
