Solution

1. Preparation

Gather tools and parts needed.
Ensure safety gear is worn (gloves, safety glasses).
Disconnect the battery to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove battery terminals, starting with the negative terminal.
2. Clean terminals with a wire brush if corroded.
3. Test the battery with a load tester; replace if it fails.
4. Reinstall the battery, ensuring tight connections.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor (usually near the transmission).
2. Disconnect the starter wiring harness and the battery cable.
3. Use a jumper wire to connect the positive terminal of the starter to the battery; check if it engages.
4. Replace the starter motor if it does not engage.

4. Ignition System Check

Sub-steps:
1. Remove the ignition coil connectors.
2. Use a multimeter to check coil resistance as per manufacturer specifications.
3. Replace any faulty ignition coils.

5. Fuel System Check

Sub-steps:
1. Locate the fuel pump relay and fuse; inspect for continuity.
2. If faulty, replace the fuel pump relay.
3. Check fuel pressure using a fuel pressure gauge; ensure it is within the specified range.
4. Replace the fuel pump if the pressure is inadequate.
