Simple Checks (Do these first):
* Fuel:
* Empty Tank: Obvious but worth checking.
* Fuel Pump: Listen for the fuel pump whine when you turn the key to the "on" position (before cranking). No whine could indicate a failed pump or relay.
* Fuel Filter: A clogged fuel filter can restrict fuel flow. This is a relatively inexpensive and easy part to replace.
* Fuel Pressure: This requires a fuel pressure gauge to check if the system is delivering adequate pressure. Low pressure points to pump, filter, regulator, or injector issues.
* Ignition:
* Battery Terminals: Corroded or loose battery terminals can interrupt the electrical system. Clean and tighten them.
* Ignition Switch: A faulty ignition switch can cut power intermittently.
* Ignition Coil: A failing coil can cause misfires and stalling.
* Spark Plugs & Wires: Worn or damaged spark plugs or wires can prevent proper combustion. Inspect for cracks, corrosion, or excessive wear.
* Distributor Cap & Rotor (if applicable): Inspect for cracks, burns, or corrosion. These components are crucial for distributing spark.
* Sensors:
* Crankshaft Position Sensor (CKP): This sensor tells the engine where the crankshaft is. A faulty sensor will prevent the engine from running.
* Mass Airflow Sensor (MAF): A dirty or faulty MAF sensor can provide inaccurate air readings, leading to stalling. Try cleaning it with MAF sensor cleaner (follow instructions carefully).
* Throttle Position Sensor (TPS): This sensor tells the computer the throttle position. A faulty TPS can cause erratic running and stalling.
More Complex Issues (Require more diagnostic tools):
* Computer (PCM): A faulty PCM can cause a wide range of problems, including stalling. This is a more difficult diagnosis and may require professional help.
* Wiring Harness: Damaged or corroded wiring can interrupt the electrical signals needed for the engine to run.
* Alternator: A failing alternator won't charge the battery, eventually leading to the engine cutting out. Test the alternator's output voltage.
* Fuel Injectors: Clogged or faulty injectors can prevent fuel from reaching the cylinders. This often requires specialized tools to diagnose.
Troubleshooting Steps:
1. Start with the simple checks: Address the easy-to-check items first (fuel, battery, ignition components).
2. Listen for unusual noises: Pay attention to any unusual sounds the engine makes before, during, or after the stalling.
3. Check engine codes: Use an OBD-II scanner to retrieve any diagnostic trouble codes (DTCs) stored in the PCM. These codes can provide valuable clues.
4. Visual inspection: Carefully examine all the components mentioned above, looking for any signs of damage or wear.
5. Seek professional help: If you can't identify the problem after thorough inspection and testing, take your Camaro to a qualified mechanic.
Important Note: Safety is paramount. If your Camaro is stalling while driving, pull over to a safe location as soon as possible to avoid an accident. Don't attempt any repairs while the engine is running.
