I ran my 450c for about an hour yesterday and when I was done, It wouldn't shut down with key off. I gave it quick check, the power to the terminal on the injector pump went cold with key off. Also, there was no throttle response with the key off, it would only idle. It's kind of a loppy idle, bouncing around a bit more than it usually does. I removed the supply line to the lift pump and let it die.
I haven't done anything more so far but I'm guessing it's a stuck open roosa solenoid but no throttle response with the key off was weird. Any quick suggestions before I start taking the winch apart?*

Re: 450C won't shut off
My guess is you have something in your solenoid valve not quite letting it close all the way. It's closing it enough it can't throttle up but not enough to kill it. Hopefully it's not a piece of the governor ring.
