Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, jumper wires, battery terminal cleaner.
Ensure the vehicle is in a safe location, and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative terminal of the battery using a socket wrench.
2. Clean the battery terminals with a battery terminal cleaner if corrosion is present.
3. Reconnect the battery terminals securely.
Tools Required: Socket wrench, battery terminal cleaner.

3. Starter Motor Testing

Sub-steps:
1. Disconnect the starter motor electrical connector.
2. Use jumper wires to connect the positive terminal of the battery to the starter motor terminal and ground the other wire to the starter body.
3. If the starter engages, it may need replacement; if not, further investigation is required.
Tools Required: Jumper wires, socket set.

4. Fuel System Check

Sub-steps:
1. Access the fuel pump relay in the fuse box under the hood.
2. Use a multimeter to test the relay for continuity; replace if faulty.
3. If the relay is functional, check the fuel pump fuse and replace if necessary.
Tools Required: Multimeter, fuse puller.

5. Neutral Safety Switch Adjustment

Sub-steps:
1. Locate the neutral safety switch on the transmission.
2. Inspect the switch for proper alignment and functionality.
3. Adjust or replace if the switch is malfunctioning.
Tools Required: Socket set.
