I know I can test glow plugs with a test light. But I cant remember or find what the ohms spec is. When I hook up my meter with plugs installed I get 1ohm on all 4 drivers and .8-.9 ohm on pass.

It's another good sign they all read the same!

Your test leads and connections constitutes most of your error. These universal volt ohmmeters aren't all that accurate trying to measure fractions of an ohm.
