Ok, so here are all the reading I got off the ECM:

Testing straight from green plug:
A1 - 0.28
A2 - 0
A3 - 0
A4 - 0
A5 - 0
A6 - 0.28
A7 - 0.28
A8 - 0
A9 - 12

A12 - not used
A13 - 0
A14 - 0.28
A15 - 11.88
A16 - 11.88
A17 - 0

Testing straight from yellow plug:

B2-B7 - 0
B8 - 11.4
B9-B24 - 0

Testing pins on yellow slot coming out of ECM (what would connect to yellow plug) WITH green plug plugged into ECM:
B1 - 0

B13 - 4.34
B14 - 4.34
B15 - 4.52
B16 - 4.34
B17 - 4.7
B18 - 4.7
B19 - 0.01
B20 - 4.34
B21 - 0
B22 - 3.4
B23 - 4.36
B24 - 0

I will check the fuel pump relay again to see if I can find anything there.
Since the ground wire that goes to thermostat is for ECM, and got shorted/burned, I bet this was the issue...?
I took pictures of the ECM, will post those to see if it helps.

Here are the pics of the ECM board. Let me know if you can see anything wrong. I am not that familiar with computer boards. I couldn't seem to find any acid leaking or notice of damage.
