Solution

1. Preparation

Gather all tools and parts needed.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Replace Air Filter (if necessary)

Sub-steps:
1. Locate the air filter housing.
2. Remove the clips or screws securing the housing.
3. Take out the old air filter and inspect the housing for debris.
4. Insert the new air filter, ensuring it fits snugly.
5. Reassemble the air filter housing and secure it with clips or screws.
Tools Required: Screwdriver set, new air filter.

3. Test and Replace Fuel Pump (if necessary)

Sub-steps:
1. Locate the fuel pump fuse and relay in the fuse box.
2. Using a multimeter, check for voltage at the fuel pump connector while the ignition is turned on.
3. If there is no voltage, trace the wiring for faults or replace the relay.
4. If voltage is present but the pump is not functioning, replace the fuel pump.
5. Reconnect all electrical connections and check for leaks.
Tools Required: Multimeter, socket set, fuel line disconnect tool, new fuel pump.

4. Replace Spark Plugs (if necessary)

Sub-steps:
1. Remove the engine cover if applicable.
