I got really busy with work for the last week and was unable to check the voltage at the pins until tonight. Both pins had 12v with the key in the on position. Is this a sign of a bad "body ECM" or "engine ECM"?

NOTE: I started getting 12v at pin 4a-8 after throwing 12v to it a few times trying to get it to start. Any advice with this.

Thanks again.

If 4B-9 and 4E-5 were both at +12 then the ECM was not pulling 4B-5 to ground, so I would say that the ECM is at fault. That also would explain why it still wont run when you manually power the fuel pump.
