Solution

1. Preparation

Gather tools including a multimeter, socket set, fuel pressure gauge, and OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean battery terminals using a wire brush to remove corrosion.
- Tighten any loose connections.
Replace Battery (if needed):
- Remove the negative terminal first, followed by the positive terminal.
- Unscrew the battery hold-down bracket and carefully lift the battery out.
- Install the new battery, securing it with the hold-down bracket, and connect the positive terminal first, followed by the negative.

3. Starter Motor Replacement (if necessary)

Remove Starter Motor:
- Locate the starter motor (typically near the transmission).
- Disconnect wiring harness from the starter.
- Unscrew the mounting bolts and remove the starter from its place.
Install New Starter Motor:
- Position the new starter in place and secure it with mounting bolts to the specified torque (usually around 30-40 ft-lbs).
- Reconnect the wiring harness ensuring a tight fit.

4. Ignition System Service

Inspect Spark Plugs:
- Remove spark plugs using a socket wrench.
- Inspect for wear or fouling; replace if necessary.
Replace Ignition Coils (if faulty):
- Remove connectors and bolts securing the ignition coils.
- Install new ignition coils and reconnect all wiring.

5. Fuel System Check

Check Fuel Pressure:
- Attach a fuel pressure gauge to the fuel rail and turn the ignition to the "on" position without starting the engine.
- Verify that pressure is within the manufacturer’s specifications (typically around 50-60 psi).
Replace Fuel Filter (if clogged):
- Locate the fuel filter (under the vehicle or in the engine compartment).
- Relieve fuel pressure before removal and replace with a new filter.
