1. Battery:
* Check the battery terminals: Are they clean and tight? Corrosion can prevent a good connection. Clean them with a wire brush and baking soda solution if needed. Reconnect securely.
* Test the battery voltage: Use a multimeter to check the voltage. It should read around 12.6V when the car is off. Anything significantly lower indicates a weak or dead battery. A local auto parts store can often test your battery for free.
* Check the battery cables: Inspect the cables for any damage, cracks, or loose connections.
2. Starter Motor:
* Listen for a click: When you turn the key, do you hear a single click? This often indicates a weak battery, a bad connection, or a failing starter solenoid. Multiple clicks might point to a low battery as well.
* Tap the starter: (Use caution!) Gently tap the starter motor with a wrench or hammer while someone tries to crank the engine. This is a risky last resort, as it can damage the starter if it's not the problem. ONLY attempt this if you're comfortable working with car parts and have ruled out other causes.
* Have the starter tested: A mechanic or auto parts store can test the starter for proper operation.
3. Ignition System:
* Check the ignition switch: Ensure the key is going fully into the ignition and turning smoothly. A faulty ignition switch can prevent the starter from engaging.
* Check fuses and relays: Consult your owner's manual to locate the fuses and relays related to the ignition system and starter. Check for blown fuses (look for a broken filament) and replace them if necessary.
* Immobilizer System (if equipped): Some Chrysler models had an immobilizer system. Make sure your key is the correct one for your vehicle and the system isn't preventing the start. A locksmith might be needed if you suspect this.
4. Fuel System:
* Check the fuel pump: Listen carefully near the fuel tank (usually in the rear) when someone turns the key to the "on" position (don't crank). You should hear a brief humming sound from the fuel pump priming the system. No sound suggests a problem with the pump, fuel pump relay, or fuel pump fuse.
* Check for fuel: Make sure you actually have fuel in the tank. Sounds obvious, but it's a common oversight.
5. Other Possibilities:
* Security system: A malfunctioning aftermarket alarm or security system could be preventing the car from starting.
* Neutral Safety Switch (automatic transmission): Ensure the gear selector is in Park (P) or Neutral (N). A faulty neutral safety switch will prevent starting.
* Sensor Problems: Various sensors (crankshaft position sensor, camshaft position sensor, etc.) can prevent the engine from starting. These require diagnostic tools to check.
What to do next:
1. Start with the simplest checks: Battery voltage, terminals, and fuses are the easiest and cheapest things to check first.
2. Listen carefully: Pay attention to any sounds (clicks, hums, etc.) when you turn the key.
3. Consult your owner's manual: It's a valuable resource for locating fuses, relays, and understanding your car's systems.
4. Seek professional help: If you're uncomfortable performing any of these checks or if the problem persists after checking the basics, take your car to a mechanic or auto repair shop for diagnosis and repair.
Remember safety first! Always disconnect the negative battery terminal before working on any electrical components. If you're not comfortable working on your car, seeking professional help is the best course of action.
