Solution

1. Preparation

Gather tools and parts required for repair.
Disconnect the negative battery terminal to ensure safety while working on electrical systems.

2. Fuel System Inspection

Sub-step 1: Remove the fuel pressure gauge and connect it to the fuel line at the fuel rail.
Sub-step 2: Turn the ignition to the "ON" position (without starting) and check the fuel pressure reading. It should be between 40-50 psi for the Corolla E170.
Sub-step 3: If pressure is low, check the fuel filter for clogs and replace if necessary.
Sub-step 4: If the filter is clear, inspect the fuel pump. Replace the fuel pump if it is not operating correctly.

3. Ignition System Service

Sub-step 1: Remove the engine cover to access the ignition coils and spark plugs.
Sub-step 2: Inspect the spark plugs for wear or fouling. Replace any damaged or worn spark plugs.
Sub-step 3: Test the ignition coils with a multimeter for resistance and replace any that are out of specification.

4. Air Intake and Vacuum System Check

Sub-step 1: Inspect the air filter for dirt and replace it if clogged.
Sub-step 2: Check for any vacuum leaks around the intake manifold and hoses; replace any cracked or damaged hoses.
Sub-step 3: Clean the mass air flow (MAF) sensor using MAF cleaner to ensure accurate readings.

5. Final Steps

Reconnect the negative battery terminal.
Clear any stored trouble codes using the OBD-II scanner.
