Default Grounded wire

So I'm thinking I have a grounded wire somewhere. I will be ripping the car apart to go through all the wiring over Christmas...then putting in a new turbo catch can auxiliary hoses and radiator hoses..if I still can't find the issue she will be going to the shop

Why look all over the car?, just look at what you touched as well as all fuses.

Have you checked OBD-II scanners on a different car to make sure the scanner/scanners work?

What were the actual codes you saw last time you could see them?

The codes that last popped were 0031 o2 sensor, 0037 o2 sensor, 0108 map sensor, 1572 immobilizer, Rhode were the last codes I seen. I did notice that when it cranks nothing moves on the rpm cluster and yes tried the scanner on the other 3 vehicles at the house.

Did you clean or replace the MAF?

If yes, remove and reinstall the connector, making sure the wires are pushed into the connector when it is clipped to the MAF.
