Wow, that photo is weird, normally the "yellow Xs" should be evenly spaced. I've never seen one set up like that before.

If you found one loose, that would be bad! Also, if one of the tabs popped out of the notch on the bracket (hard to explain), this can also cause a no-fuel problem on a particular cylinder. I've seen one pump like this. I should duplicate the problem on a core/junk pump and take a photo. Basically make sure all linkages on each cylinder look identical and that none are loose.

Yup, anything visibly broken would also be bad.

If you screw up any of the adjustments, it has to go to a Bosch shop for calibration, and probably a rebuild too. You can safely remove the side cover for a visual inspection, just keep tools away from there. Order a new gasket before you take the cover off, as the old gasket will most likely be fossilized and not seal well.
