The rack position sensor plug has a base that rotates normal "off" direction by finger, but it may be really tight and not obvious. That plug must come off to get the vacuum shut off valve off. 'Tis doable under the intake manifold, but if you pull the pump you could also do a complete re-seal at the same time and then not worry about the pump for another 100k miles. Might also be able to get a clean shot at all the glow plugs with the pump out of the way.

It is a lot easier to do on the IP core on the bench, than on the working one under the intake manifold. I have been pondering buying a manifold gasket, but I think I will try taking off the ALDA and the electric plug, then pull the shutoff and see if anything is apparent. Since I have a working plastic shutoff, I may plug that in and see it if makes a difference, if nothing is apparent when I take out the old metal shutoff. > Fred Moir wrote: >> Just a thought, if the metal shut-off vaccu-suck were to bind in its' slide, >> it >>might cause the problem that you describe. > > I suppose Loren could remove the vacuum shutoff, and see if the shut-off, the >hand stop lever, or neither has binding when they're apart.
