I have a 2007 pilot. I have to replace the knock sensor harness which was chewed by some woodland creature. How do I relieve the fuel pressure just in case I have to remove the fuel rails to get to the sensor???

I don't think that Honda has a schroeder valve on the fuel rail--I wish they did! One way to bleed the fuel pressure from the system is to remove the fuel pump relay from the fuse block, preventing the fuel pump from operating. Now try to start the engine. It may fire a couple of times and die, or it may not fire at all. In either case, the operation of the fuel injectors should drain the pressure from the fuel rails.

Great tips. They’re stored away in my memory bank if I ever need to relieve fuel system pressure.
If you use the Schaeder valve would you place a plastic bag or the likes over the valve to prevent fuel from spraying all over the place?
