Sundays update. Woke up early eager to troubleshoot the ECU. I went through all the checks per the FSM and to my surprise everything checked out. This is good news because it leaves me with the only logical conclusion that it is the injectors themselves. During all this testing and cranking, i'm getting the feeling that the engine is running for a very tiny bit longer and longer as the days go on. This also reinforces the notion that the injectors are frozen from years of sitting.
I decide to bite the bullet and I remove the upper manifold so I can take a peek at the injectors. I took one out that looked the driest and sprayed some cleaner in it an let it sit for ten minutes. Blew it out with the air hose and then cycled it with battery voltage one just to hear it click. I reassembled the injector rail and upper manifold hoping to hear it run even longer, but to my surprise it caught on perhaps two cylinders which was enough to stay running and then a third caught and finally the fourth. After a minute or two the engine was purring with no smoke or vibrations. I'm not positive but think the problem was gummed injectors. I have no CEL and so I added water to the radiator which showed me a leak at the lower hose. I will fix that at a later time as I'm done in for the day.
