Safety Warnings: Ensure the vehicle is in park or neutral with the parking brake engaged. Disconnect the negative battery terminal before starting work.

2. Access Fuel Pump

Remove Rear Seat Cushion:
- Locate the clips or bolts securing the rear seat cushion and remove them.
- Lift the cushion to access the fuel pump access panel.
Remove Access Panel:
- Unscrew the bolts securing the access panel and carefully lift it off to expose the fuel pump assembly.

3. Test Fuel Pump Operation

Connect Fuel Pressure Gauge:
