Good morning gents, I have spent hours searching with no answer to be found. I have a stuck rail on a 6-71. The funny thing was it wasn't stuck yesterday. I prep'ed the engine for a run and made sure everything was working, rail movement and all. Today I hooked the battery up and checked the rail one more time and the damn thing is stuck open. I tried to pry it shut and it won't move. Any idea would be great. I will be working on it again hopefully this evening. Thanks Paul (oh yea, I've narrowed it down to one particular injector)
