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 battery to avoid any electrical hazards.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery cables (negative first, then positive).
2. Clean any corrosion from the terminals and cable ends using a wire brush.
3. Test the battery with a multimeter; if it shows less than 12.4 volts, replace the battery.
4. Install a new battery if necessary and reconnect cables (positive first, then negative).

3. Starter Motor Testing and Replacement

Sub-steps:
1. Locate the starter motor under the vehicle.
2. Disconnect the wiring harness and battery cable from the starter.
3. Use a multimeter to test the starter; if it does not engage, replace it.
4. Install the new starter motor and reconnect the wiring.

4. Fuel System Check

Sub-steps:
1. Locate the fuel pump relay and check its operation.
2. If the relay is functioning, connect a fuel pressure gauge to the fuel rail.
3. Turn the ignition to the "ON" position (without starting) to check for pressure; it should be within manufacturer specifications.
4. If pressure is low, inspect the fuel pump and replace if necessary.
