[QUOTE="2Barrels, post: 66236, member: 9217"] Well, on Saturday I went down to another dealer - not so local. Service manager there was helpful. Though he did not have any recent knowledge of the Isuzu 3KC pump he suggested that there was either a C-clip or something similar holding things up. Showed me some service manuals. One manual - for a Mitsubishi diesel - showed a long spring hook to the rod/pin I was referring to. Came back home and took another look. This time with magnifiers on and lo and behold, there's a long spring hooked over the rack control (the rod/pin I have been referring to.) Reached in with a needle nose, grabbed the spring and removed it. Pump lifted out w/o further issue. Tuesday, pump and injectors will be off to the diesel injection service center for testing, rebuild and/or replacement. One thing the service manager did recommend was that I turn the engine over by hand and take a look at the cam lobes to see if there were any major signs of wear. I did so, and didn't note any unusual wear. He said that since the pump is 'timed' by shims, as long as I didn't loose or change the order that the shims came out, replacement and timing shouldn't be an issue. I hope he's right. When I took the pump out, there was only one shim - looks more like a gasket, but I was sure to leave it undisturbed. [/QUOTE]
