1. The Basics
* Battery Connections: Double-check that the battery terminals are securely connected. Corrosion can prevent a good connection. Clean the terminals with a wire brush if needed.
* Battery Charge: While new, ensure the battery is fully charged. It may have a slight charge from the store, but it's best to connect it to a charger for a few hours.
* Starter: Make sure the starter motor is getting power. You can try jumping the car to see if it starts. If it does, the starter may be failing.
2. Beyond the Battery
* Ignition System:
* Spark Plugs: Worn or fouled spark plugs can prevent the engine from igniting.
* Spark Plug Wires: Cracked or damaged wires can interrupt the spark.
* Ignition Coil: A faulty coil can fail to generate the spark needed.
* Distributor (if applicable): Inspect the distributor cap and rotor for wear or cracks.
* Fuel System:
* Fuel Pump: A failing fuel pump may not deliver enough fuel to the engine.
* Fuel Filter: A clogged fuel filter can restrict fuel flow.
* Fuel Lines: Check for leaks or blockages in the fuel lines.
* Engine Management System:
* Sensors: Sensors like the crankshaft position sensor (CPS) and camshaft position sensor (CMP) send crucial information to the engine control unit (ECU). A faulty sensor can prevent the engine from starting.
* ECU: Though less likely, a faulty ECU can prevent the engine from starting.
Troubleshooting Tips
* Check for Spark: With a spark plug wire disconnected, hold the end near a grounded metal surface. The spark should jump when you crank the engine.
* Check for Fuel: If there's spark but no start, check for fuel delivery. Remove a fuel line at the injector rail, and crank the engine. You should see fuel coming out.
Important Notes:
* Professional Assistance: If you're not comfortable with automotive repairs, it's best to consult a qualified mechanic.
* Safety First: Always disconnect the battery before working on the electrical system.
