Starts, runs rough for 30 seconds, then it shuts off or just will not start?

The picture you posted was the turbo? And yes, you may have moved the transaxle mount bolt. I think maybe you should tow it to a shop. If it is not starting, I would recommend that you look at the fuel pump control module as previously recommended.

In the second picture, are those the two bolt holes that you removed? If so, to the left there looks like an engine mount to me. Here's a picture of the throttle body, if it was part of the transmission/transaxle that moved, I think you may have pulled the wiring harness apart, the code you're getting (U0073) is a network no communications code, it's probably why your scan won't communicate either. If the CANbus network, which is a 2-wire network, either shorted out together or both shorted to ground it would take the whole network down. Try to get things back together first, you may have to put a jack under the transaxle to lift it into position to get the bolts back in. Also check for any wiring harnesses that either got pulled apart or if any connectors were pulled apart. I'm pretty sure you're going to find a damaged harness due to the new issues you're having.
The third diagram is the info on the CANbus A network, and the fourth diagram are the two wires for the network (green and white).

That is why you need to inspect it first to verify that is the issue. If you see corrosion on the terminals, then that is your issue with the no start.

No, its most likely just the harness in the area where things moved around. I wouldn't scrap it unless you had planned on getting rid of it. But if things are too much to handle then I would follow what Jorge said. Just relay everything that happened to the shop you take it to, so they have an idea of what happened.

Inspect the fuel pump module before doing the pump. The harness as mentioned earlier is a pigtail and not the body harness. Trust me, I have done a body harness on your vehicle model, and it is not fun.
