Honda 17045-SJC-A01 Set, Fuel Pump Module

Before checking Honda models from 2005 forward and Acura models from 2003 onward one must verify fuel presence in the tank then activate the fuel pump by switching to ignition ON to hear a brief whirring sound. A high-pressure fuel gauge needs an adapter to measure fuel pressure by connecting at the firewall opening of the fuel system. Disconnect the fuel lines only after monitoring the system pressure drops and cutting off all power from the battery terminal. You must first remove the fuel supply line quick-connect fitting then connect a fuel pressure gauge to that port. Next step is to reconnect the battery followed by turning the ignition switch to ON status while observing the fuel pump operation for two seconds alongside pressure readings on the gauge. Begin the engine operation while monitoring until it gets to normal operating temperature. Record the observed fuel pressure reading. The correct working condition indicates of the system when pressure measurements stay within designated specifications. A reading below the specification requires checks for leaks along the fuel lines as well as assessment of the fuel filter clog to determine whether the fuel pump/fuel level sending unit module needs replacement. You should replace the fuel pressure regulator because its pressure readings stay beyond the predetermined range. To finalize testing you must first withdraw system pressure then disconnect the battery terminal then take out your testing rig before reattaching the fuel supply line followed by restoring the terminal connection to start the engine for fuel leak detection.
