Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery cable to prevent electrical shorts.

2. Fuel System Inspection

Check Fuel Pump
- Remove the fuel pump relay from the fuse box.
- Use a multimeter to test the fuel pump voltage while turning the ignition to the ON position (not starting).
- If voltage is absent, replace the fuel pump.
Replace Fuel Filter
- Locate the fuel filter along the fuel line.
- Use a socket set to disconnect the fuel lines (be cautious of residual fuel).
- Install a new fuel filter ensuring correct orientation.

3. Ignition System Service

Inspect Spark Plugs
- Remove the ignition coil covers if applicable.
- Use a spark plug socket to remove the spark plugs.
- Inspect for wear; replace any damaged or worn spark plugs with OEM equivalents, torquing to specifications (typically 13-15 lb-ft).
Replace Ignition Coils
- Unscrew the coils from the engine.
- Disconnect the electrical connectors.
- Install new ignition coils and reconnect the connectors.

4. Air Intake and Exhaust Inspection

Check Air Filter
- Open the air intake housing.
- Remove and inspect the air filter for dirt and blockages; replace if necessary.
Inspect Exhaust System
- Examine for any leaks or blockages, particularly in the catalytic converter.

5. Transmission Fluid Change

Check Fluid Level
- Locate the transmission dipstick.
- Check the fluid level; add fluid if low.
Change Transmission Fluid
- Drain the old fluid using a drain pan.
- Replace the transmission filter and gasket, and refill with manufacturer-recommended transmission fluid.
