Simple Checks (Do these first!):
* Fuel:
* Empty Tank: The most obvious! Check your fuel gauge.
* Fuel Pump: Listen for the fuel pump whirring when you turn the key to the "on" position (before cranking). If you don't hear it, the pump might be failing.
* Fuel Filter: A clogged fuel filter can restrict fuel flow.
* Battery/Electrical:
* Battery Terminals: Corrosion on the battery terminals can prevent a good connection. Clean them thoroughly.
* Battery Voltage: Test the battery voltage. A weak battery can't provide enough power to keep the engine running.
* Alternator: While it starts, the alternator might be failing to charge the battery. A failing alternator will cause the car to die once the battery's initial charge is used.
* Ignition System:
* Crankshaft Position Sensor (CKP): This sensor tells the computer the position of the engine. A faulty CKP will prevent the engine from running consistently or at all.
* Cam Position Sensor (CMP): Similar to the CKP, a faulty CMP will also cause starting and stalling issues.
* Ignition Coil: A weak or failing ignition coil can cause misfires and stalling.
* Ignition Switch: The switch itself might be faulty.
More Complex Issues (Require a Mechanic or Advanced Diagnostics):
* Computer/PCM (Powertrain Control Module): A faulty PCM can cause numerous problems, including starting and stalling issues. This often requires professional diagnostics.
* Mass Airflow Sensor (MAF): This sensor measures the amount of air entering the engine. A faulty MAF can cause a lean or rich fuel mixture, leading to stalling.
* Throttle Position Sensor (TPS): Similar to the MAF, a faulty TPS can cause incorrect fuel delivery.
* Fuel Injectors: Clogged or faulty fuel injectors can prevent proper fuel delivery.
* Vacuum Leaks: A leak in the vacuum system can disrupt engine operation.
Troubleshooting Steps:
1. Start with the simple checks: Battery terminals, fuel level, fuel pump sound.
2. Listen carefully: Does the engine sputter, cough, or make unusual noises before it dies? This can give clues.
3. Check engine codes: Use an OBD-II scanner to retrieve any diagnostic trouble codes (DTCs). These codes can pinpoint the problem area.
Important Note: Without further diagnostics, it's impossible to say for certain what's wrong. If the simple checks don't reveal the problem, you should take your Camaro to a qualified mechanic for proper diagnosis and repair. Attempting to diagnose and fix complex electrical or fuel system issues without the proper knowledge and tools can be dangerous.
