Well I got a good bit done last night.
I changed out the ICM. The car still didn't start. Ew that made me mad. I thought, O.K., the ECM is bad, let me change that out. I changed that out and as I did I found these pin holding clips laying below the ECM.
So basically the plug was connected but could have had a pin or more come loose.
So I plug in the new to me ECM and see on the large plug where the clips were off the Green and white wire not all the way in and prolly, MAYBE the reason why the fuel pump wasn't getting signal.
So I pushed in the ECM plug pin clips to make sure the pins are properly seated. I feel better thinking that was the inconsistant problem all along.
Well, I get the ECM installed correctly and check everything to be correct. Go to start the car and it doesn't start again. No Fuel Pressure still.
So I start thinking.......
My last ditch effort really..... I grab a extra grounding cable I have and attach it to one of the intake bolts and back to the negative of the battery. The car starts right up.
I think that was my problem all along. Bad Grounding somewhere or everywhere. Now I have perminantly installed a extra ground wire to the block.
I next moved on to replacing the Fuel Pressure regulator. I pulled off the top of the intake and found, what I had assumed, that the EGR tube was bad. The top part that attaches to the intake had already been welded VERY poorly and was leaking. I removed it and found that it was covered up with a Aluminum can piece at the intake. It wasn't working to begin with. Anyways I am fixing it with a 1/2" Natural Gas flex pipe. I cut off the ends that came with it and re-flanged them into the original EGR Tube ends. So far it looks and fits great. I won't know until I get done re-painting the intake and re-installing.
But here are the ends I made up.
