Ok with the light staying on your computer is not comunicating so it is probably a bad prom. I will look further into that.
The fuel pump relay is inside the car on the passanger side behind the dash.
With all that you have said you have been finding it sounds like the computer is doing what it wants when it wants. I would first check grounds to the computer make sure none are shorted.
Here is what you need to do now to test the PCM ok. Jump Term A and B again turn key on and see if anything has changed If light still stay's on then turn key of leaving jumper in place and disconnect the PCM and then turn key back on and see if the light came on if it did then you need to repair the short in the brown and white wire.
If the light stayed off then check to make sure the PROM is poperly installed if it is then disconnect the battery to clear codes and then reconnect and check the light again if there are no changes then the PROM is bad. Now what needs to be figured out is why is this car killing computers by checking ground to the computer. Let me know what you find.
