SteveKran I've compared one of craftsman's cheaper multimeters to my expensive fluke 89 and the craftsman is fairly accurate.
As far as you readings on your multimeter, are you saying that you are getting .4 megaohms? If you are, that's probably way to high. Check out this thread, NCHornet is a pretty knowledgeable person on this subject. http://www.powerstroke.org/forum/gen...g-gpr-gps.html
That is the article I found and was referring to when I did the testing yesterday - though it doesn't indicate to have the ignition forward when testing the GP's (sorry, it's obvious I'm totally new to this particular field, rarely used a multi meeter for anything but checking voltage) and your right, my initial post of 0.4 was totally incorrect
with the meeter set @ 2m (milli) I get .004 and I get 0.04 when set to 20k with ignition forward - off I get .000 and 0.00 respectively.

Lastly your glowplugs should read from .1 to .6 Ohms you can do this with everything pluged in and one lead on the negative battery the other lead on the wire for that glowplug. hope this helps
With the test light hooked to positive then hitting the outer most 2 prongs in the receiving plug on the valve cover the light goes on (same thing with the male plug, makes sense) with the test light grounded bumping the ignition forward to activate the GPR I get nothing - I knew it was dead, I jumped the GPR with a screwdriver while the test light was contacting a prong and it lit up right away.
I appreciate your patience wi
