Fuel Pressure Inspection
- Relieve fuel pressure in fuel feed line referring to "FUEL PRESSURE RELIEF PROCEDURE: ".
- Disconnect fuel feed hose (3) from delivery fuel feed pipe (1).CAUTION: A small amount of fuel may be released when fuel feed hose is removed. Place container under the fuel feed hose or fuel feed pipe with a shop cloth so that released fuel is caught in container or absorbed in cloth. Place that cloth in an approved container.
- Connect special tools and hose (2) between fuel feed hose (3) and fuel feed pipe (1) as shown in figure, and clamp hose securely to ensure no leaks occur during checking.

- Check that battery voltage is above 11 V.
- Turn ignition switch ON to operate fuel pump and after 3 seconds turn it OFF. Repeat this 3 or 4 times and then check fuel pressure.
- Start engine.
- Measure fuel pressure at idling.
If measure pressure doesn't satisfy specification, refer to FUEL PRESSURE CHECK and check each possibly defective part. Replace if found defective.
Fuel pressure specification
- After checking fuel pressure, remove fuel pressure gauge (1).CAUTION: As fuel feed line is still under high fuel pressure, make sure to release fuel pressure according to the following procedures.
- Place fuel container under joint.
- Cover joint with rag and loosen joint nut slowly to release fuel pressure gradually.
- Remove fuel pressure gauge, hose and 3-way joint.
- Connect fuel feed hose and clamp it securely.
- With engine OFF and ignition switch ON, check for fuel leaks.
