Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to avoid any electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the negative (-) battery cable, followed by the positive (+) cable.
2. Inspect the battery for corrosion on terminals; clean if necessary using a mixture of baking soda and water.
3. Test the battery voltage with a multimeter; replace if voltage is below 12.4 volts.
4. If replacement is needed, install a new battery and reconnect the positive cable first, then the negative cable.

Tools Required:

Multimeter
Wrench set
Battery terminal cleaner

3. Fuel System Service

Sub-steps:
1. Locate the fuel pump fuse and remove it.
2. Start the engine to relieve fuel pressure, then turn the ignition off.
3. Replace the fuel filter if it hasn't been changed recently, as a clogged filter can impede fuel flow.
4. Reconnect the fuel pump fuse and start the engine.

Tools Required:

Fuel filter
Pliers
Safety glasses

4. Spark Plug Inspection and Replacement

Sub-steps:
1. Disconnect the ignition coils from the spark plugs.
2. Remove the spark plugs using a spark plug socket.
3. Inspect the spark plugs for wear or fouling, replacing them if they are worn beyond specifications.
4. Gap the new spark plugs according to manufacturer specifications and install them, ensuring they are torqued to the correct value.
