Solution

1. Preparation

Ensure the vehicle is parked on a level surface, and the engine is off.
Gather necessary tools and parts for the repair.

2. Check Fuel Pump Operation

Tools Required: Fuel pressure gauge, multimeter.
Steps:
1. Disconnect the negative battery terminal to avoid electrical shock.
2. Remove the access panel to the fuel pump if applicable.
3. Use the multimeter to test the voltage at the fuel pump connector while the ignition is in the "on" position. It should read approximately 12V.
4. If there is no voltage, inspect the fuel pump relay and fuse for continuity and replace if necessary.

3. Test and Replace Fuel Pump (if needed)

Tools Required: Socket set, fuel line disconnect tool, torque wrench, safety goggles.
Steps:
1. Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
2. Disconnect the negative battery terminal and fuel lines from the fuel pump assembly.
3. Remove the fuel pump assembly from the fuel tank following manufacturer-specific instructions.
4. Replace the fuel pump with a new unit and ensure it is seated properly.
5. Reconnect the fuel lines and reassemble any access panels.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Turn the ignition to the "on" position and listen for the fuel pump to prime.
Attempt to start the engine.
