Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before starting any work.

2. Address Fuel Delivery Issues

Fuel Filter Replacement
- Locate the fuel filter; it may be in-line or part of the fuel pump assembly.
- Use a wrench to disconnect fuel lines (be cautious of residual fuel).
- Remove the old filter and install the new one, ensuring correct orientation.
- Reconnect the fuel lines securely.
Fuel Pump Inspection
- Check the fuel pump operation by listening for a humming sound when the ignition is turned on.
- If the pump is faulty, remove the fuel tank access panel and disconnect the fuel lines.
- Replace the fuel pump assembly if necessary, ensuring proper sealing upon reinstallation.

3. Inspect Ignition System

Spark Plug Replacement
- Remove the ignition coils or spark plug wires using the appropriate tools.
- Remove the spark plugs using a spark plug socket.
- Inspect the spark plugs for wear or deposits; replace if necessary with OEM or equivalent parts.
- Reinstall the new spark plugs and reconnect ignition components.

4. Transmission Fluid Change

Drain and Replace Transmission Fluid
- Raise the vehicle securely on jack stands.
- Remove the transmission pan bolts and drain the fluid into a suitable container.
- Replace the transmission filter (if applicable) and reinstall the pan with a new gasket.
- Refill the transmission with the manufacturer's recommended fluid type.
