Unplugged connector A, turned key to ON position, connected Fuel pump fuse, heard click from rear of vehicle and also click from under dash relay. What are your thoughts? ECU?

Don't let this thread scare you of what "could" happen. Had I just removed the components for the APS, installed simulator, and left the electrical alone, I would have been driving the car and enjoying it as the mod as intended.

just don't start cutting or removing wiring and you'll be fine

Clicking but the pump does not run continuously like it did before? If you plug back connector A again and the problem comes back, then yes most likely the ecu has been damaged.
Not sure what to think about that clicking though.

Have you ruled out incorrect installation of the fuel pump delete module? Have you removed it and checked if the problem persists?

flanders

Fuel pump delete module, that would be something
But yes the air pump sim might be causing troubles as well, if that is installed.

Yes sir, that was the first thing I did after recognizing the fuel pump kept priming.

I've tried it both ways actually. Installed and uninstalled. I may just try it again for the hell of it.

Can you splice the cut harness back in?

Borrow a friend's ECU and test it before you buy a replacement. It's a pain to make another ECU work as you'll need the immobilizer or to get it programmed. All you'll need is the donor key to test another one.

When you were cutting out wires, did you cut them one at a time, or were you cutting multiple wires at once? Reason I ask, is because if you were cutting multiple wires at one time, you could have easily fried something.
