Once again all 6 glow plugs are brand new (less than 3k miles) and they are getting voltage for sure. Have toggle on dash that activates relay which is audible, and have tested the bus bar for voltage.
I like the clear fuel line idea... yeah fuel solenoid is getting voltage and presumably working correctly due to fuel pressure at all cylinders, correct? Still dont know anything about injectors themselves tho... Again its been a couple months since trying to start... today i'll get him in the garage and give another go before looking at valves. I'm really leaning towards rings unfortunately but trying to eliminate all other possibilities first. I do remember getting some ignition in at least a couple cylinders when trying to start on ether before... Just wouldnt catch only a little noise per revolution...If I can figure my crappy camera out might make a video for you guys (stepped on the iphone, Doh!) And thanks everyone this is awesome to have some support while wading into the unknown here!!!

If you are getting spurts of fuel out of the injector line ends during cranking then we can say your fuel cutoff solenoid is working. Next test is clear fuel line at the IP in/outs.

Yes glow plugs were getting ether daily for at least a month... didn't realize it could fry them that quick!!

very much so. that's why I suggest testing load from that rather than their supply.
When I start my bench engine, I hold a jumper to the glow wire and count to 12, drop that and hit the starter. It fires right up. No need for fancy electronics.

You can also get an idea of plugs' condition testing with an ohmmeter or test light. Good plug will have relatively low resistance to ground, dead plug will be open. Usually this is an accurate test although not always, however, gives you some idea at least. Only trouble is that you have to detach the bus bar from all 6 plugs in order to test accurately, with them all hooked up this test only tells you whether or not they are *all* dead.
Or, if you have access to an ammeter with fairly high current capacity, you can check current thru the supply wire from the GP relay and get a pretty close idea of how many plugs are working and how many are dead (though you won't know which ones are which). Each plug will draw about 12 amps after a couple seconds. Fully functioning system should give you 72 amps, getting 48 amps means only 4 are live, 24 amps means 2, etc, etc. A little inductive meter that you hold next to the cable (e.g. the type sold for checking alternator charging current or starter draw) works reasonably well for this. I pulled some plugs out of a 6.9L Ford once that was getting ether every morning. The tips had exploded. Pretty violent event when that stuff goes off and if the plugs are hot at the time, it's not good. A last idea would be to pull out a few of the easily accessible plugs on your motor (cyls 1-4). Appearance of what comes out of there might give you some clues as to what's keeping it from lighting off.

Ya don't see this everyday! Not recommended for highway travel LOL getting Ronald in the garage finally... took almost a week to make room it was near hoarder status... More pics shortly I'm gonna go fetch some clear fuel line and rob the new battery my dad got for his tractor and start crankin on it again
