Update on my electrical progress. I really have it narrowed down at this point. So, i checked the ground for the ecu (at the thermo-stat housing) and cleaned the electrical connector and the mounting point really good. Then I re-assembled and checked with the volt meter again. Grounds at pins 9, 10, 22 and 23 are all at .3-.5 volts now. Great, got that one taken care of. I double checked my fuses and re-checked the pins that should be showing voltage. The pins that actually power up the ECU are still reading almost nothing. So, i have a power issue. I was doing some research and i learned that one of the possibilities is the main relay. The main relay power-out wire is Yellow/black or black/yellow, i forget which at the moment. The wires that are reading 0 at the ECU power pins are the same colors. So i track down the main relay and unbolt it for examining. First, i checked for the click with the key in the on position. It was very noticeable, it clicked on. However, the CEL is not turning off with a second click. At this point, I reconnected my scan tool and it was unable to make a connection with the vehicle. I suppose this makes sense, since there is no power going to the ECU. So, upon examining the main relay, i noticed some oddly placed electrical tape. I remove it and find this, someone's attempt at a repair at some point (not me, I don't ever recall doing this).
Now, I don't think this is the issue though. The wire that is repaired poorly is yellow and green, which according to the book powers the fuel pump. It will be fixed correctly. So, a few things i need to research.
1. How to de-pin the main relay plug so that I can replace this shoddy repair.
2. How to diagnose the main relay to determine if the relay itself is bad and is causing my ECU issue
3. If the relay checks out fine, how to determine which wire is bringing power to the main relay, and verify that this wire is getting power.
