    250 series with Kawasaki engine won't run. There's no power to the fuel pump but if 12 volts is applied to the pump (jumped out) the pump will run for 5-10 minutes without the jumper applied if the key is on.
    Somewhere there must be a relay or switch that controls the pump, but we can't find it. The wiring diagram shows a OPC relay that controls the fuel pump but we can't find it or understand its function.
    Any ideas?

    The problem ultimately proved to be a relay up front that controlled the fuel pump. There's a new relay part number that replaces the old one and should stand up better.
