Solution

1. Preparation

Gather 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 shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Use a multimeter to check the battery voltage; it should be above 12.4 volts.
2. Clean the battery terminals with a wire brush.
3. If the voltage is low, recharge or replace the battery.
Tools Required: Multimeter, wire brush, battery terminal cleaner.

3. Fuel System Check

Sub-steps:
1. Locate the fuel pump fuse in the fuse box and inspect it for continuity.
2. If functional, use a fuel pressure gauge to check for proper fuel pressure; it should be within the manufacturer's specifications.
3. If pressure is low, inspect the fuel filter and replace it if clogged.
4. If the fuel pump is faulty, replace it.
Tools Required: Fuel pressure gauge, replacement fuel filter, basic hand tools.

4. Ignition System Inspection

Sub-steps:
1. Remove spark plugs and inspect for wear or fouling; replace if necessary.
2. Use an ignition coil tester to check the ignition coils; replace any that are defective.
3. Reinstall spark plugs and reconnect ignition components.
Tools Required: Spark plug socket, ignition coil tester.

5. Reassembly and Battery Reconnection

Sub-steps:
1. Reconnect the negative battery terminal.
2. Ensure all components are secured and tools are removed from the engine bay.
Tools Required: Basic hand tools.
