Basic Checks:
* Battery: Check the battery terminals for corrosion, and the battery's voltage. A weak battery can prevent the car from starting. A fully charged battery should have around 12.6 volts.
* Starter: Check the starter solenoid for clicking sounds when you turn the key. If you hear a click but the starter doesn't engage, the starter motor itself could be faulty.
* Fuses: Inspect the fuse box for blown fuses, especially those related to the ignition system, fuel pump, and starter.
* Connections: Check all electrical connections for corrosion, loose wires, or broken wires. Pay attention to the battery terminals, starter cables, and ignition switch wiring.
Ignition System Issues:
* Ignition Switch: A faulty ignition switch can prevent power from reaching the starter. Try wiggling the key while turning it to see if it affects the starting.
* Ignition Coil: A faulty ignition coil can prevent spark from reaching the spark plugs. You can test the coil using a multimeter.
* Distributor: Problems with the distributor, including a worn distributor cap, rotor, or points, can disrupt the spark delivery.
* Spark Plugs and Wires: Worn or fouled spark plugs can prevent the engine from firing. Inspect the spark plugs and replace them if necessary. Inspect the spark plug wires for cracks or damage.
Fuel System Issues:
* Fuel Pump: A faulty fuel pump will not deliver fuel to the engine. You can check the fuel pump by listening for a humming sound when you turn the key to the "on" position.
* Fuel Filter: A clogged fuel filter can restrict fuel flow to the engine.
* Fuel Injectors: Clogged or faulty fuel injectors can prevent fuel from reaching the cylinders.
* Fuel Relay: A malfunctioning fuel pump relay will prevent the fuel pump from receiving power.
Other Electrical Components:
* Computer Control Unit (ECU): A faulty ECU can disrupt the engine's operation, preventing it from starting.
* Sensors: Numerous sensors, like the crankshaft position sensor, camshaft position sensor, and oxygen sensor, can affect the engine's starting. A malfunctioning sensor may send incorrect signals to the ECU.
Troubleshooting Tips:
* Use a multimeter: A multimeter is an essential tool for diagnosing electrical problems. It can help you test the battery, fuses, ignition coil, and other components.
* Consult a repair manual: A repair manual specific to your 1987 Camaro will provide detailed instructions on how to test and diagnose electrical systems.
* Look for warning lights: Some electrical problems can be indicated by warning lights on the dashboard, such as the "Check Engine" light.
* Seek professional help: If you're not comfortable diagnosing electrical problems yourself, it's best to take your Camaro to a qualified mechanic.
Remember, when working with electrical systems, always disconnect the battery to avoid shocks.
