#138055, "No power to ECU, car won't start. Please help!"


          

I own a 95 GS and it's worked fine until 1 day I go to start it and it would crank and crank but not start. I quickly realized the check engine light wasn't coming on, and the fuel pump and ASD relays weren't clicking.
I did as much diagnosing as I could but could really use some help. I've checked all the fuses especially the 30 amp engine fuse and all are good. I get 12V to 2 pins on the ASD relay so that looks goods. Only things I can find is that the black/red wire going into the ECU at pin 2 has no power going to it and I think it's suppose to be main power for the ECU according to this http://www.2gnt.com/index.php?d=1995_ECU

.... So I checked for reference voltage to all the sensors and everyone is below 1 volt but higher than half a volt with the key on. Any help would be appreciated.
