Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wrench set, fuel pressure gauge.
Safety Warnings: Disconnect the battery before working on electrical systems. Ensure the vehicle is in park and the engine is cool.

2. Battery Replacement (if necessary)

Disconnect the negative terminal from the battery.
Remove the positive terminal from the battery.
Unbolt the battery hold-down clamp and carefully lift out the battery.
Install the new battery in reverse order, securing the hold-down clamp.
Reconnect the positive terminal first, followed by the negative terminal.

3. Fuel System Inspection and Repair

Locate the fuel pump relay and inspect it for continuity; replace if defective.
Connect a fuel pressure gauge to the fuel rail and start the engine to check for adequate pressure (refer to manufacturer specifications).
If pressure is low, consider replacing the fuel filter or the fuel pump.

4. Starter Motor Replacement (if necessary)

Disconnect the battery again for safety.
Remove the electrical connections from the starter motor.
Unbolt the starter motor from its mounting (refer to specific torque specs for your model).
Install the new starter motor, tightening bolts to the manufacturer’s specifications.
Reconnect the battery and test the starter functionality.
