Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Ensure the vehicle is parked on a level surface with the engine off and cooled down.

2. Inspect and Replace Fuel Pump (if faulty)

Tools Required: Fuel pressure gauge, socket set, screwdrivers, safety glasses, gloves.
Sub-steps:
1. Remove the fuel pump relay from the fuse box.
2. Disconnect the fuel lines from the fuel pump assembly (use safety glasses to protect eyes from fuel spray).
3. Remove the fuel pump assembly from the fuel tank.
4. Replace the old fuel pump with the new one.
5. Reinstall the fuel pump assembly into the fuel tank and secure it.
6. Reconnect the fuel lines and reinstall the fuel pump relay.

3. Check and Repair Ignition System

Tools Required: Multimeter, socket set, spark plug socket.
Sub-steps:
1. Remove the spark plugs using the spark plug socket.
2. Inspect spark plugs for wear and replace if necessary.
3. Test ignition coil resistance using a multimeter; replace if out of specification.
4. Reinstall new or cleaned spark plugs and secure them properly.

4. Inspect Battery and Charging System

Tools Required: Multimeter, battery terminal cleaner.
Sub-steps:
1. Check the battery voltage using a multimeter; it should read at least 12.6 volts when fully charged.
2. Clean battery terminals and cable connections to ensure good contact.
3. If voltage is low, recharge or replace the battery as needed.
4. Test the alternator output at idle; it should read between 13.8 - 14.4 volts.
