If you does not have 5V - so first mission find out where it gone. It is very important for any engine ECU. It is hardware problem - wiring, power supply, engine ECU.

Not familiar with that car, but disconnect all sensors that use the 5V reference one at a time to see if it comes back. Any one of them could be shorted. The exceptions will be IAT and ECT, they will not affect 5V reference.

If someone took the time to help you, the least you can do is take a few seconds and press two buttons!
