Solution

1. Preparation

Gather your tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shock or short circuits.

2. Battery Inspection and Replacement

1.1 Remove the battery terminals (negative first, then positive).
1.2 Inspect the battery for corrosion and clean terminals with a wire brush if necessary.
1.3 Test the battery with a multimeter; if below 12.4 volts, replace it.
1.4 Install the new battery by connecting the positive terminal first, followed by the negative.

3. Fuel System Repair

2.1 If fuel pressure is low, replace the fuel filter and inspect the fuel pump.
2.2 Disconnect the fuel lines and replace the fuel filter if it is clogged.
2.3 Reconnect the fuel lines and prime the system by turning the ignition on without starting the engine to build pressure.
2.4 If the fuel pump is faulty, replace it according to the manufacturer's specifications.

4. Ignition System Maintenance

3.1 Remove the spark plugs using a socket wrench.
3.2 Inspect the spark plugs for wear or carbon buildup; replace if necessary.
3.3 Check the ignition coils for proper function; replace any that are defective.
3.4 Reinstall the spark plugs and ensure they are torqued to the manufacturer's specifications.
