Solution

1. Preparation

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

2. Inspect Fuel System

Sub-steps:
1. Remove the fuel pump fuse and start the engine to relieve fuel pressure.
2. Disconnect the fuel line at the fuel rail using a wrench (be cautious of fuel spillage).
3. Use a fuel pressure gauge to measure fuel pressure. Compare readings with manufacturer specifications.
4. If pressure is low, replace the fuel pump.
Tools Required: Fuel pressure gauge, wrench set, safety glasses.

3. Check Ignition System

Sub-steps:
1. Remove spark plug wires and inspect for wear or damage.
2. Use a spark tester to check for spark at each spark plug.
3. If no spark is present, replace faulty ignition coils or spark plugs as necessary.
Tools Required: Spark tester, socket set.

4. Address Vacuum Leaks

Sub-steps:
1. Inspect all vacuum hoses for cracks or disconnections.
2. Replace any damaged hoses with OEM or equivalent parts.
3. Reconnect all hoses and ensure they are securely fastened.
Tools Required: Pliers, hose cutter.

5. Reassemble and Test

Sub-steps:
1. Reconnect the fuel line and install the fuel pump fuse.
2. Reconnect the negative battery terminal.
3. Start the engine and monitor for smooth operation and stalling.
Safety Warnings: Ensure the engine is cool before working on components.
