Solution

1. Preparation

Gather tools and parts for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative terminal of the battery to ensure safety.

2. Inspect Fuel Pump Fuse

Locate the fuse box and find the fuse related to the fuel pump.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for any signs of damage; replace if blown.

3. Test Fuel Pressure

Connect a fuel pressure gauge to the Schrader valve on the fuel rail.
Turn the ignition to the "ON" position without starting the engine.
Read the pressure on the gauge; it should meet manufacturer specifications (usually around 30-60 PSI).
If the pressure is low, replace the fuel pump.

4. Check Battery and Connections

Inspect the battery terminals for corrosion; clean them if necessary.
Tighten any loose connections.
Test the battery voltage with a multimeter; if below 12.4 volts, consider recharging or replacing the battery.

5. Inspect Ignition System

Remove spark plugs and inspect for wear or damage; replace as needed.
Test ignition coils with a multimeter to ensure they are functioning within specifications.
Reinstall components after inspection.
