Sorry to post a non MB subject but more sorry that I've been working in cold rain for two days trying to get a '99 NPR diesel to start and run. I had some of the fuel hoses off so problem is undoubtedly air. I've checked all connections 10 x (will do it again in the morning). Worked primer pump until fuel flowed from opened bleed bolt. Tried cracking injector lines at injectors and cranking with starter. Thought it might be a failed fuel shut off solenoid and removed what I believe (HOPE) is that solenoid, which of course turns out to be functioning just fine except I can't see if it needs to attach to anything or just be screwed back in place. Frustrated...who, me?! I've got 6 diesels and this one - not mine - makes me feel like a complete beginner. Anyone have Isuzu specific experience or a service manual? Snow's coming and I've got to get this thing out of here!! Thanks for any and all suggestions. Nothing too simple - you never know!
