Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool down before starting work.

2. Inspect and Replace Faulty Components

A. Fuel System Check

Fuel Pump Inspection
- Remove the access panel to the fuel pump.
- Use a multimeter to measure the voltage at the pump connector; it should match the specifications (usually around 12V).
- If the pump is not functioning, replace it with a new OEM part.
Fuel Filter Replacement
- Locate the fuel filter under the vehicle; use a socket set to remove it.
- Install a new filter, ensuring it’s oriented correctly.

B. Ignition System Service

Spark Plug Inspection
- Remove spark plug wires and use a socket to extract the spark plugs.
- Examine plugs for wear or carbon build-up; replace if necessary.
Ignition Coil Replacement
- Disconnect the electrical connector from the ignition coil.
- Remove bolts securing the coil; replace with a new coil and reconnect.

3. Clean or Replace Sensors

MAF Sensor Cleaning
- Remove the MAF sensor from the air intake duct.
- Use MAF sensor cleaner to clean the sensor element; allow to dry before reinstalling.
Crankshaft Position Sensor Replacement
- Locate the crankshaft position sensor (usually near the crankshaft pulley).
- Disconnect the electrical connector and remove mounting bolts; replace with a new sensor.
