Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Sub-steps:
1. Inspect battery terminals for corrosion and clean if necessary using a wire brush.
2. If the battery voltage is low, replace the battery with a new one (12V, 600 CCA recommended).
3. Reconnect the positive terminal first and then the negative terminal.
Tools Required: Battery terminal cleaner, wrench set.
Safety Warnings: Wear gloves and safety goggles to protect against battery acid.

3. Starter Motor Testing and Replacement

Sub-steps:
1. Remove the starter motor from the vehicle by disconnecting the electrical connections and unbolting it from the engine.
2. Bench test the starter motor using a jump starter or battery to confirm if it engages.
3. If faulty, replace with a new starter motor and reassemble in reverse order.
Tools Required: Socket set, wrench set, jump starter.
Safety Warnings: Ensure the battery is disconnected before working on electrical components.

4. Fuel System Check and Repair

Sub-steps:
1. If the fuel pump is not operating, check the fuel pump relay and fuses for continuity.
2. If faulty, replace the relay or fuse as needed.
3. If the pump is operational but still not delivering fuel, replace the fuel pump.
Tools Required: Multimeter, socket set, fuel line disconnect tool.
Safety Warnings: Relieve fuel pressure before disconnecting fuel lines to avoid sprays.
