  07 reading ZERO fuel pressure but runs??

  Posted by Chris on June 6, 2023 at 11:17 pm

  Got an 07 kingpin that will suddenly not keep idle and has stalled a couple of times. I stuck a fuel pressure gauge on it and it’s reading zero. The bikes starts fine and runs! How can this be? Bad schrader valve possibly? For what its worth, I tried the following prior to checking the fuel pressure:

  Tried 2 good batteries with wrench tight connections, found no vacuum leaks by spraying brake cleaner around throttle body boots, etc., good plugs and wires, multiple throttle point resets, which seemed to help the first few times it happened but does nothing now.

  Any similar experiences or recommendations? I don’t understand how the bike could start and run with no pressure. What could be up?

  Thanks in advanceGot an 07 kingpin that will suddenly not keep idle and has stalled a couple of times. I stuck a fuel pressure gauge on it and it’s reading zero. The bikes starts fine and runs!
