FUEL PRESSURE EC-489 < PERIODIC MAINTENANCE > [VK56DE] C D E F G H I J K L M A EC N P O PERIODIC MAINTENANCE FUEL PRESSURE Fuel Pressure Check INFOID:0000000009886934 FUEL PRESSURE RELEASE With CONSULT 1. Turn ignition switch ON. Without CONSULT 1. Remove fuel pump fuse located in IPDM E/R. pressure. 4. Turn ignition switch OFF. FUEL PRESSURE CHECK CAUTION: • Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger. • Be careful not to scratch or get the fuel hose connection area dirty when servicing, so that the quick connector o-ring maintains sealability. • Use Fuel Pressure Gauge Kit J-44321 and Fuel Pressure Adapter J-44321-6 to check fuel pressure. • Do not perform fuel pressure check with electrical system operating (i.e. lights, rear defog, A/C, etc.). Fuel pressure gauge may indicate false readings due to varying engine loads and changes in mani- fold vacuum. NOTE: Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres- sure cannot be completely released because A60 models do not have fuel return system. EM-27, "Removal and Installation" . • Do not twist or kink fuel hose because it is plastic hose. • Do not remove fuel hose from quick connector. • Keep fuel hose connections clean. 4. Install Fuel Pressure Adapter J-44321-6 and Fuel Pressure Gauge (from kit J-44321) as shown in figure. • Do not distort or bend fuel rail tube when installing fuel pres- sure gauge adapter. • When reconnecting fuel hose, check the original fuel hose for damage and abnormality. 5. Turn ignition switch ON (reactivate fuel pump), and check for fuel leakage. 6. Start engine and check for fuel leakage. • During fuel pressure check, check for fuel leakage from fuel connection every 3 minutes. BBIA0380E BBIA0390E |
