Solution

1. Preparation

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

2. Inspect Fuel System

Tools Required: Fuel pressure gauge
Sub-steps:
1. Connect the fuel pressure gauge to the Schrader valve on the fuel rail.
2. Turn the ignition to the "ON" position (do not start) and check the fuel pressure reading.
3. If pressure is below specifications (typically around 50-60 psi), proceed to check the fuel pump.

3. Replace Fuel Pump (if necessary)

Tools Required: Socket set, fuel line disconnect tool
Sub-steps:
1. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
2. Disconnect the negative battery terminal.
3. Raise the vehicle and remove the fuel tank access cover if applicable.
4. Disconnect fuel lines and electrical connectors from the fuel pump assembly.
5. Remove the fuel pump assembly and replace with a new pump.
6. Reassemble by reversing the removal steps and reconnecting the battery.

4. Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth
Sub-steps:
1. Remove the air intake duct connecting to the throttle body.
2. Spray throttle body cleaner onto a soft cloth and wipe the interior of the throttle body.
3. Ensure the throttle plate moves freely and is not obstructed.
4. Reattach the air intake duct securely.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle for several minutes.
Monitor for any warning lights and ensure the engine runs smoothly.
