    6.9 motorhome giving new grief

    A few weeks ago I got help getting my project motorhome going (thanks again). We took it camping a few days ago and drove it about 160Km (75 miles) and it ran pretty good except the common and annoying issue of occasionally stalling after dropping the throttle too quickly. I adjusted the idle up...

    Filter is fine. I dont know the pressure but it seems to pump a lot. Cracking any of the lines it sprays fuel like crazy. I plan on replacing it the next few days as maintenance item.

    Next thing on the list. She starts and runs fine but it has this strange problem of stalling when you stab the throttle. And while this rig is completely new to me and don't know what to expect, it seems awfully sluggish and throttle response is very slow. Its a big motorhome and not sure what I...

    At long last found the problem. After endless cranking I eventually got fuel dribbling out the injector lines. I tightened them up and nothing. I've gone through glow plug circuit and getting 12v to plugs, bad plugs replaced. I replaced all the return line components and hoses, including O-rings...

    Just took another look and checked the glowplugs. 2 were burned out and one had been accidentally disconnected. All three were on lines that eventually showed fuel while cranking. What I'm thinking happened is that the air leak allowed the high pressure lines to drain but not all to the same...

    This is where it's gotten complicated, and more so than the other threads I've read where the solution was straightforward. I have to assume batteries and starter are good because on the first time when I bled the system and got it started, once I saw fuel at injectors I closed them off and it...

    That's very useful, thanks. Interestingly the only possibility they have for no fuel at injectors is faulty FSS and the advance solenoid. I didn't know that the advance solenoid was required to have 12v when starting and I'll have to check it out. Lots of good info on testing glow plug circuits...

    Ive got 3/4 of a tank, but fuel pressure to the IJ pump seems good.

    No water separator on this rig... Gp are the only thing I think I haven't checked, because I did it get it started that first time.

    Hey all, I've done a lot of reading on the subject but I think my lack of experience with this rig is showing. Ive worked on a lot of 4 cylinder diesels but not a V8. Background is that I bought a nice '86 project motorhome cheap, primarily because it had a rare diesel engine. It was a...
