Solution

1. Preparation

Tools Required: Multimeter, OBD-II scanner, fuel pressure gauge, socket set, torque wrench.
Disconnect the negative battery terminal before starting any repairs.

2. Battery Replacement

1. Remove Old Battery:
- Disconnect the negative terminal first, then the positive terminal.
- Remove any securing brackets or straps holding the battery in place.
2. Install New Battery:
- Position the new battery in the tray and secure it with brackets.
- Connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Replacement (if needed)

1. Remove Starter Motor:
- Locate the starter motor, typically found near the engine block.
- Disconnect the battery if not already done.
- Unplug the electrical connector and remove mounting bolts using a socket set.
2. Install New Starter Motor:
- Position the new starter motor in place and secure it with mounting bolts, torquing to manufacturer specifications.
- Reconnect the electrical connector securely.

4. Fuel System Inspection and Repair (if needed)

1. Check Fuel Pump Operation:
- Turn the ignition key to the "ON" position without starting the engine and listen for the fuel pump activation sound.
2. Replace Fuel Filter:
- If the fuel pressure is low, consider replacing the fuel filter as it may be clogged.
