* Spark Plugs: Remove the spark plugs and check if they are worn out or damaged. If they are, replace them with new spark plugs.
* Spark Plug Wires: Check the spark plug wires to see if they are cracked or damaged. Replace any damaged wires.
* Distributor Cap and Rotor: Check the distributor cap and rotor for any cracks or damage. If either are damaged, replace them.
* Fuel Filter: Check the fuel filter to see if it is clogged. A clogged fuel filter can prevent fuel from reaching the engine. If it is clogged, replace the fuel filter.
* Air Filter: Check the air filter to see if it is dirty or clogged. A dirty air filter can restrict air flow to the engine. If it is dirty or clogged, replace the air filter.
* EGR (Exhaust Gas Recirculation) Valve: Check the EGR valve to make sure it is not stuck open or closed. A stuck EGR valve can cause the engine to run poorly.
* Idle Air Control (IAC) Valve: Check the IAC valve to make sure it is working properly. A faulty IAC valve can cause the engine to idle poorly or not start at all.
* Engine Coolant Temperature (ECT) Sensor: Check the ECT sensor to make sure it is working properly. A faulty ECT sensor can cause the engine to run rich or lean, affecting starting.
