To be clear, I'm not very adept when it comes to diesel engines and fuel systems, but I think I can do my best to explain what is going on
I have a jayco RV with a 6.9 in it and just under 70k miles on the whole setup. There is a definite problem with the injection pump where I'm getting very poor fuel economy and power loss since it was purchased years ago
This is what i do know. It starts up, cold idles fine, then the idle drops down. If i drive it, problems start.
I don't know what the thing is actually called, but there's a metal lever that pushes in on a plunger type thing on the right side of the pump (right side if you're facing the engine from the hood) If i take a screwdriver and pry out on this lever, the truck seems to return to normal. I can't say I know exactly what this thing does, i've been trying to do as much reading as possible but haven't found my answer. There is no fuel leaking anywhere that i can tell. Is this simply something that is somehow gummed up and getting stuck? The truck did sit for a long period of time.
I'm obviously trying to get this thing back on the road and in good running condition. I've looked at some diagrams of injection pumps but can't find any good information on what this part is even called, so i've dubbed it "sticky lever thing that's making my life suck"
When it gets stuck the truck idles like crap and smokes a lot. Any ideas? suggestions on solutions (possibly without removing the pump??)
Any help is appreciated, and I'm gonna eep trying to read up more to see if I can find my answer
Thanks for any help
