1. The Basics:
* Battery: This is the most common culprit. Check the battery terminals for corrosion. Clean them with a wire brush and baking soda and water solution. Test the battery voltage with a multimeter. It should read around 12.6 volts when not cranking. If it's low, charge it or replace it.
* Battery Cables: Inspect the cables for damage, looseness, or corrosion. Make sure they're securely connected to both the battery and the starter.
* Starter: Try tapping the starter with a hammer or wrench (be careful!). A failing starter can sometimes be temporarily revived this way. If it's consistently failing to engage, it needs replacement.
2. Does it Crank?
* Cranking = Yes: If the engine cranks (turns over) but doesn't start, the problem lies in the ignition system, fuel system, or engine itself. We'll address these below.
* Cranking = No: If the engine doesn't even crank, the problem is likely with the battery, cables, starter, or ignition switch. Focus on those areas mentioned in step 1.
3. If it Cranks but Doesn't Start:
* Fuel System:
* Fuel Pump: Listen for the fuel pump to prime when you turn the key to the "on" position (but don't crank). You should hear a brief whirring sound. If not, the fuel pump relay, fuse, or pump itself may be faulty. This requires further investigation and potentially testing the fuel pressure.
* Fuel Filter: A clogged fuel filter can restrict fuel flow. Replacing it is relatively inexpensive and can solve the problem.
* Fuel Injectors: These can become clogged or fail. Diagnosis usually requires specialized tools or a mechanic.
* Ignition System:
* Spark Plugs & Wires: Check the spark plugs for fouling (black, wet, oily) or damage. Inspect the spark plug wires for cracks or damage. A simple replacement can fix a misfire. You can test for spark using a spark plug tester.
* Distributor (if applicable): If your Camaro has a distributor, check the rotor and cap for cracks or wear. Replace as needed.
* Ignition Coil: This component provides the high voltage needed for spark. A faulty coil can prevent the engine from starting.
* Engine:
* Timing Belt/Chain: If the timing belt/chain has broken or jumped teeth, the engine won't start. This is a serious issue requiring professional attention. Listen for unusual noises if you can crank the engine.
* Sensors: Several sensors (crankshaft position sensor, camshaft position sensor, etc.) are crucial for engine operation. A faulty sensor can prevent the engine from starting. Diagnosis usually requires a scan tool to check for codes.
4. Using a Scan Tool (Recommended):
A scan tool can read diagnostic trouble codes (DTCs) stored in the car's computer. These codes can pinpoint the problem with much greater accuracy. Auto parts stores often offer free code reading services.
5. When to Call a Mechanic:
If you're not comfortable working on your car, or if the problem persists after checking the basics, it's best to take it to a qualified mechanic. Some issues, like timing belt/chain problems, fuel injector issues or sensor failures, require specialized knowledge and tools.
Remember safety first! Disconnect the negative battery terminal before working on any electrical components. If you are unsure about any step, consult a repair manual or professional. A 1995 Camaro repair manual can be invaluable in this process.
