Ensure the vehicle is on a flat surface and securely supported.

2. Inspect and Replace Fuel Pump (if necessary)

Sub-steps:
1. Remove the fuel pump access panel (if applicable) or lift the vehicle to access the fuel tank.
2. Disconnect the electrical connector from the fuel pump.
3. Disconnect the fuel lines from the pump using a fuel line disconnect tool.
4. Remove the retaining ring and lift the fuel pump out of the tank.
5. Compare the old pump to the new pump for compatibility.
6. Install the new fuel pump in the reverse order of removal.
Tools Required:
- Fuel line disconnect tool
- Socket set
- Torque wrench
Safety Warnings:
- Relieve fuel system pressure before disconnecting any fuel lines.

3. Inspect and Replace Spark Plugs and Ignition Coils (if necessary)

Sub-steps:
1. Remove the engine cover (if applicable) to access the ignition components.
2. Disconnect the electrical connectors from the ignition coils.
3. Remove the ignition coils using a socket set.
4. Remove the spark plugs using a spark plug socket and inspect for wear or fouling.
5. Replace with new spark plugs and re-install the ignition coils.
Tools Required:
