Popped the top off the pump....this its what was in there....pretty sure the weight retainer shouldn't spin independently of the main shaft and have so much slop. I'd say she's toast. https://youtu.be/028iCfToxbk

Thanks for the input guys. I'm talking with Scott over at Oregon Fuel Injection as it seems people have had good results there. The pump that is on there is a 4267 pump. I know that's not the military number which I believe are obsolete. Its HD civvy one so I think they are more or less the...

Ya I think the ring has failed and it just hasn't run enough to see debris from the ring. The local injection shop quoted $900 to do the pump so I guess I'll be finding one online since that's pretty steep for a POS rotary pump.

Well after replacing all the valve springs on the drivers side bank I pulled the injector pump cover off and there are a bunch of metal shavings in there. They are ferrous and stuck to the solenoids. From what I could see the governor assembly looks ok, but with the shavings in there something...

Good info. Sorry, I didn’t see your post in my other thread. Just took a look and no tag on the pump. It was supposed to be a new rebuilt one when the shop did it 8 years ago but I was 400miles from home so I was more focused on getting up and running than what specific updates were done. I’m...

Engine Over Revving When Started Hey guys, I'm having a problem that just popped up recently and resulted in a broken valve spring. Now that the valve spring is taken care of I am back to troubleshooting the original issue. When I start the truck it acts like the pedal is floored / its running...

Well I put a new valve spring in there and she runs normally now as far as the knock and misfire go. Still revving when started. Now that its back to a working engine I can start troubleshooting the rev issue, but Ill start a new thread for that since its pretty specific.

That's what I originally thought, but since it doesn't blow any white / blue smoke or look like there is oil leaking from the valve guide I'm thinking it might be something else. Once I have a chance to get the valve spring changed out I'll post an update.

I did some more work today and found some stuff. First off, no smoke (other than black). I have to start it and throw it in gear to keep the revvs down. When it sits there trying to go in gear both pipes are blowing some black, but nothing out of the norm. I pulled the drivers side valve cover...

Hey Guys, I'm having some engine trouble with the M1009 that has me a bit stumped. I drove it to work the other day and everything was swell. When I started it to go to lunch as soon as it started it revved way up to ~3k like the throttle was stuck open, but before I had a chance to acknowledge...
