Simple Checks (Do these FIRST):
* Dead Battery: This is the most frequent culprit. Check the battery terminals for corrosion (clean them if needed) and have the battery tested at an auto parts store. A weak battery might crank slowly or not at all.
* Loose or Corroded Battery Cables: Even if the battery is good, loose or corroded cables can prevent a proper connection. Inspect and clean them thoroughly.
* Faulty Starter: The starter motor engages the engine to crank it. A failing starter can make a clicking sound when you turn the key, or simply fail to engage.
* Empty Fuel Tank: Sounds obvious, but a completely empty tank can prevent the car from starting.
More Complex Issues:
* Alternator Problems: The alternator recharges the battery while the engine is running. A failing alternator will drain the battery over time, eventually preventing the car from starting.
* Ignition Switch Issues: The ignition switch might be faulty, preventing power from reaching the starter or other essential components.
* Faulty Ignition Coil or Spark Plugs/Wires: These are crucial for ignition. Worn or damaged spark plugs, wires, or ignition coil will prevent the engine from firing.
* Fuel Pump Problems: The fuel pump delivers fuel to the engine. A faulty fuel pump will prevent fuel from reaching the engine. You might hear a humming sound from the fuel pump when you turn the key if it's failing.
* Security System Issues: Some Sebrings have anti-theft systems that might prevent starting if there's a problem with the system or the key fob.
* Neutral Safety Switch: This prevents the car from starting unless it's in park or neutral. A faulty switch can prevent starting.
* Computer Problems (PCM/ECM): The Powertrain Control Module (PCM) or Engine Control Module (ECM) controls many engine functions. A faulty computer can cause a wide range of issues, including no start. This is less likely but possible.
* Immobilizer Issues: The immobilizer system prevents the car from starting if it doesn't recognize the key.
Troubleshooting Steps:
1. Start with the simple checks: Battery, cables, fuel level.
2. Listen for sounds: Clicking from the starter, humming from the fuel pump, etc. can provide clues.
3. Check the fuses: A blown fuse can prevent power from reaching certain components.
4. Use a multimeter: This will help you test the battery voltage, and check for power at various points in the electrical system. (This requires some electrical knowledge)
5. Consult a repair manual: A repair manual specific to your 2000 Chrysler Sebring will provide detailed diagrams and troubleshooting steps.
If you're not comfortable working on your car yourself, it's best to take it to a qualified mechanic for diagnosis and repair. Describing the symptoms (e.g., "it cranks but doesn't start," "it makes a clicking sound," etc.) will help the mechanic narrow down the possibilities.
