Strange Inj Pump Failure

[RCP]

Oliver 1655 with a Standyne injection pump with apparent governor failure, throttle position has no impact on engine RPM and you have to use the kill cable to control engine RPM or the engine tries to run away.

Before this problem started the throttle rod cam into contact with the hot post on the starter and got hot enough to burn the paint from the throttle rod, it appears that the throttle rod was grounded through the fuel injection pump.

Would this have caused a governor failure?

Thanks

Pop the top cover off the pump and look in. I cannot say I have ever heard of a scenario like you describe, but who knows? If you are sure it was working okay until battery-positive power hit the throttle-arm and then after that heat - the problem showed up? If that IS indeed the case, it is possible the throttle-rod got its ground via the fuel metering valve or its linkage and that is what controls the throttle. If that IS the problem, you will easily see it once the top of the pump is off.
