Fuel Pressure Test |
1. |
Release the residual pressure in fuel line.
(Refer to Fuel Delivery System - "Release Residual Pressure in Fuel Line")
|
2. |
Install the Special Service Tool (SST).
|
3. |
Inspect fuel leakage on connections among the fuel feed tube, the high pressure fuel pump, and the SST components with IG ON. |
4. |
Measure Fuel Pressure.
|
5. |
Release the residual pressure in fuel line.
(Refer to Fuel Delivery System - "Release Residual Pressure in Fuel Line")

6. |
Test End
|
Release Residual Pressure in Fuel Line |
Whenever the high pressure fuel pump, fuel pipe, delivery
pipe, or injector is removed immediately after shutting off the engine,
an injury may be caused by the release of highly pressurized fuel.
Release the residual pressure in the high pressure fuel line by
referring to the "Residual fuel pressure release procedure" below before
removing any high pressure fuel system components.
|
Wear safety glasses and fuel resistant gloves.
|
1. |
Turn the ignition off and disconnect the battery negative cable. |
2. |
Remove the fuel pump fuse (A). |
3. |
Disconnect the electrical connector from the high pressure fuse pump. |
4. |
Reconnect the battery negative cable. |
5. |
Run the engine for about 20 seconds to lower the pressure in
both the high or low pressurelines. The engine may shut off within the
20 second period. If not, turn the engine off. |
6. |
Proceed with the service or repair. Use rags to cover opening and catch spills when opening up the high pressure system. |
7. |
Reinstall / re-connect all components in reverse order of
removal. Start engine and confirm proper operation, and make sure there
are no fuel leaks. |
8. |
After completing, clear DTC(s) using GDS scan tool (the procedure described above will cause DTC to set). |
