Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and cool.
Disconnect the battery to prevent electrical shock.

2. Fuel System Inspection

Sub-step 1: Remove the fuel pump relay and check for proper voltage at the fuel pump connector.
Sub-step 2: If no voltage is present, inspect the fuel pump fuse and wiring for damage.
Sub-step 3: Replace the fuel filter if it is clogged and ensure that the fuel lines are free of kinks.

3. Ignition System Repair

Sub-step 1: Remove spark plugs and inspect for wear or carbon buildup; replace if necessary.
Sub-step 2: Test the ignition coils with a multimeter to ensure they are functioning within specifications.
Sub-step 3: Replace any faulty ignition components and reassemble.

4. Sensor Replacement

Sub-step 1: Disconnect the MAF and TPS connectors.
Sub-step 2: Use a multimeter to test the sensor outputs against specifications.
Sub-step 3: Replace any malfunctioning sensors and reconnect the connectors.

5. Vacuum Leak Repair

Sub-step 1: Inspect all hoses connected to the intake manifold for cracks or disconnections.
Sub-step 2: Use a smoke machine or carburetor cleaner to locate vacuum leaks.
Sub-step 3: Replace or repair any damaged hoses to restore proper vacuum levels.
