More likely you have a meter that can't differentiate between 0 ohms and
1 ohm.
But yes, it is possible to have all 5 GPs grounded. not common at all,
but possible
the most common source of grounding when new GPs have been installed is
the terminal on the gp wire turning as the nut is tightened. Generally,
the terminal needs to be held away from the intake manifold with a paint
paddle stick screwdriver, or if you can reach, your fingers. You can
see all the terminals with the manifold installed, but for some it is
easier to see if you kneel on the radiator mount. (pay homage to Herr
Rudolf)

*Please clarify the comments in red below. Are you talking about the
plug that attaches to the 5 prongs of the Relay and provides power to
each GP? If so, I checked each 'socket' and it returned 0.0
ohms. Is that telling me all 5 plugs are grounded either in the GP
or the wiring?*

You don't need to reach all the glow plugs with your multimeter, you can
check for shorts at the small plug which plugs into the glow plug relay.
1st things 1st, indeed!
The first thing, however, is measuring the resistances seen at the small
plug to ground.
Do not put the new relay in before you do that.

Thx Kaleb,
The relay in my 91 is a replacement, I replaced it a couple years
after I bought it.
Well, I have more fuses and a new relay so I plan to put the new relay
in and see what happens. Actually that's a easier procedure than
trying to reach all those GPs with a MM. Worst case, I'll pull the
fuel lines and take a closer look at the wiring harness. 1st things
1st, ;-)
Thanks for the help gang!

What's the cut off for "New" vs "old"? or is it all 602 & 603? I ask
because the relay from the dealer for my '91 came with a fuse across
the bottom.
Thx
Larry

Thanks, I guess MB didn't issue one for the W124 602 engine?
