Thanks, Erps. I got the plunger unstuck by removing top of chamber and going in from the top. I placed a socket on the stuck plunger head and tapped it lightly and it dropped out the bottom of the chamber. Order four new springs from a diesel injection specialist shop, who informed me that my particular pump
does not have a rebuild kit. He said he could not quote me a price to rebuild it because he would have to take it apart and see what all it needed. I replied that I've already done that and there are 3 broken springs. He said he would have to do it himself in order to quote me a price. He said I was asking for trouble because the pump
would have to be calibrated after being rebuilt. I asked how much that would cost, and he said he couldn't say because he would have to rebuild it himself in order to calibrate it. He said I would have to take certain measurements according to the specs (which he said there was no way I could get) in order to attempt to calibrate it. I can't see where any measurements of any kind are called for. All the pieces go back together again in only one way, the way they came out. I don't see anything to measure or calculate. Am I missing something crucial? I ordered four new springs from him anyway which were 8 dollars apiece, and freight was $20.00 more from Wisconsin to Florida. Am I asking for more serious engine damage, as he said, if I put the pump
back together and reinstall it without paying him an unknown figure to rebuilt & calibrate it?
