Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, wrenches, and safety gloves.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative (-) battery terminal using a wrench.
2. Clean any corrosion from the battery terminals with a wire brush.
3. Reconnect the terminals securely.
4. If battery voltage is low (below 12.4 volts), replace the battery with a new one (ensure it matches specifications).

3. Starter Motor Testing and Replacement

Sub-steps:
1. Disconnect the wiring harness from the starter motor.
2. Remove the starter motor using a socket set; typically, there are 2-3 bolts securing it.
3. Test the starter motor with a multimeter to check for continuity.
4. If faulty, install a new starter motor, aligning it properly, and torque the bolts to manufacturer's specifications.

4. Fuel System Check

Sub-steps:
1. If the fuel pump is not operational, access it by removing the rear seat or trunk panel (as applicable).
2. Disconnect the fuel lines and electrical connector from the fuel pump.
3. Replace the fuel pump if it fails the operational test (ensure to relieve fuel system pressure before disassembly).
4. Replace the fuel filter if clogged or restricted.
