Is My ECU dying ???

Since Thanksgiving Ive been having some car issues. First she left me stranded, a least in front of my house, with a no start situation. After doing some tests, I found here and with some major help, we found out wire 85 ground of DME relay was not working and we decided to put a toggle switch for the moment. car running fine, no issues, just had to remember to turn off switch. Now she has a new symptom, she is activating the DME relay but not the fuel pump, (fuel pump relay is tested good) same situation no ground on wire 85 to trigger relay. So,No fuel pump relay, no fuse 18 voltage and no fuel pump voltage. I tried giving it a ground, and heard the fuel pump clearly, but the sound I was getting in the beginning in the motor like the injector valves receiving fuel, was not present, she won't start. I was hoping maybe I had some ground problems. Took out pin connector of ECU and according to ETW I did continuity tests on the six grounds, only three were good. I'm kninds worried in buying a DME and that not be the problem. Also I believe I have EWS II installed. New DME or borrowed won't do any good unless it's aligned with key, module, and DME. What do you think ?
