Solution

1. Preparation

Gather tools and parts needed.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection

Sub-steps:
1. Clean the battery terminals using a wire brush and a solution of baking soda and water.
2. Check the battery voltage; it should be above 12.6 volts. If below, consider replacing the battery.
Tools Required: Multimeter, wire brush.

3. Starter Motor Check

Sub-steps:
1. Remove the starter motor from the vehicle (refer to service manual for specific instructions).
2. Test the starter motor by connecting it directly to a power source to see if it engages.
3. Replace the starter motor if it fails the test.
Tools Required: Socket set, jumper cables.

4. Fuel System Inspection

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail and turn the ignition to the "ON" position (do not start the engine).
2. Check the pressure reading; it should be within the manufacturer’s specifications (refer to service manual).
3. If pressure is low, inspect the fuel pump and replace if necessary.
Tools Required: Fuel pressure gauge, socket set.
