Fuel Line Pressure Inspection

1. Disconnect negative battery cable.
2. Release fuel system pressure.
3. Raise a vehicle.
4. Install SST(0K2A1 131 001A) to fuel filter as shown.
5. Connect negative battery cable.
6. Connect data link connector terminals FUEL PUMP and B+ with jumper wire.
7. Turn ignition switch ON.




8. Inspect the fuel line pressure.

Fuel line pressure: 46 - 51 psi (320 - 350 kPa, 3.2 - 3.5 kg/sq.cm)

Pressure too high:
- Check for restricted fuel return line
- If line is clean, replace pressure regulator Pressure too low:
- Clamp return line and check if pressure rises
- If pressure does rise, replace pressure regulator.
- If pressure does not rise, measure fuel pump maximum pressure.

9. Turn ignition switch OFF and remove jumper wire.
