Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and basic hand tools.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Battery Inspection

Sub-step 1: Reconnect the negative terminal after checking the battery voltage.
Sub-step 2: Clean any corrosion from battery terminals using a wire brush.
Sub-step 3: Tighten battery connections to ensure a good electrical connection.

3. Fuel System Check

Sub-step 1: If the fuel pump was not heard during the ignition ON position, access the fuel pump relay and test it for functionality.
Sub-step 2: If the relay is operational, test the fuel pump with a fuel pressure gauge to ensure it is delivering the correct pressure (typically around 30-40 PSI for Corolla).
Sub-step 3: If the pump is not functioning, replace the fuel pump assembly.

4. Ignition System Check

Sub-step 1: Remove a spark plug wire and inspect for damage.
Sub-step 2: Insert a spark plug tester into the spark plug wire and crank the engine; observe for a spark.
Sub-step 3: If there is no spark, check the ignition coil(s) and replace as needed.

5. Final Steps

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Attempt to start the vehicle after all checks and repairs.
Sub-step 3: If the vehicle starts, clear any error codes with the OBD-II scanner.
