2.3.7.7 Fuel Pressure Testing Procedure
Warning!
Gasoline and gasoline vapor is highly flammable. In order to avoid fire or explosion, please select keep away from a
fire. It is prohibited to use mobile phones during this procedure. Do not use open containers to store gasoline exhaust
emissions. Before carrying out this procedure, please prepare a dry-chemical fire extinguisher.
Warning!
Wrap a cloth around the fuel pressure gage and fuel rail joints to absorb leaked fuel when you connect the fuel pressure
gage to reduce the risk of fire and injury. Upon completion of testing, place the cloth into the designated containers.
Clean pipe joints before removal.
Warning!
It is prohibited to pour or store fuel in an open container, otherwise it will cause a fire.
Install fuel pressure gage in the fuel rail intake.
Step 1
Next
Place the fuel pressure gage exhaust hose into a specified gasoline container.
Step 2
Next
Open the valve on the fuel pressure gage to discharge the air from the gage.
Step 3
Next
Step 4 Turn the ignition switch to "ON" position.
Next
Step 5 Use scan tool "Function Test" drive fuel pump fuel pump relay, until all the air expelled from pressure gage.
Next
Step 6 Turn off the exhaust valve on the fuel pressure gage.
Next
Use scan tool to connect the fuel pump to check whether there is fuel leakage and the leakage location.
Step 7
Next
When there is no leakage in the pipeline, start the engine and the fuel pressure should be 400 kPa (58.01
Step 8
psi).
Next
Turn the ignition switch to "OFF" position. under normal circumstances the system should maintain residual
Step 9
pressure above 250 kPa (36.26 psi). If the fuel pressure continues to drop, check the fuel pump or fuel
pressure regulator.
