Solution

1. Battery Check and Replacement

Sub-steps:
1. Disconnect the negative terminal of the battery.
2. Remove the battery and take it to an auto parts store for testing.
3. If the battery is weak or defective, replace it with a new one.
4. Reinstall the battery, ensuring the terminals are clean and properly tightened.

Tools Required:

Wrench set
Battery terminal cleaner

2. Starter Motor Inspection and Replacement

Sub-steps:
1. Disconnect the battery again for safety.
2. Remove the starter motor by disconnecting the wiring harness and bolts.
3. Test the starter motor using jumper cables to check if it spins freely.
4. If defective, install a new starter motor by reversing the removal steps.

3. Fuel System Check

Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Connect a fuel pressure gauge to the port.
3. Turn the ignition to the "ON" position (do not start) to check fuel pressure readings.
4. If the pressure is below specifications (around 40-50 psi), inspect the fuel pump and replace if necessary.

Tools Required:

Fuel pressure gauge

4. Ignition System Inspection

Sub-steps:
1. Remove the spark plugs using a socket wrench.
2. Inspect the spark plugs for wear or carbon buildup. Replace if necessary.
3. Check the ignition coils for proper operation using a multimeter.
