Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Check Battery Health:
- Remove the battery from the vehicle using a socket set.
- Clean the terminals with a wire brush if corroded.
- Test the battery with a load tester; replace if it fails to hold charge.
Replace the Battery (if necessary):
- Install a new battery, ensuring it matches the specifications for your model.
- Tighten the terminals securely and reconnect the negative terminal.

3. Starter Motor Service

Inspect and Test Starter:
- Remove the starter motor from the vehicle by disconnecting the wiring and unbolting it.
- Test the starter motor with a bench test to evaluate its functionality.
- Replace the starter motor if it fails the test.

4. Fuel System Check

Inspect Fuel Pump:
- Locate the fuel pump relay and ensure it is functioning; replace if faulty.
- Connect a fuel pressure gauge to the fuel rail to check for adequate fuel pressure.
- Replace the fuel filter if it is clogged or dirty.

5. Ignition System Service

Check and Replace Spark Plugs:
- Remove the spark plugs using a spark plug socket.
- Inspect for wear or damage; replace if necessary.
- Ensure that the gap is set to the manufacturer's specifications.
