I know that touching the cables together sounds strange. What happens when you disconnect the battery the energy is removed from the vehicle's electrical systems. When you touch the cables together you depleting the stored energy inside all the computers. The vehicle's computers have a type of battery (not an actually battery), capacitors to be exact and touching the cable completes the circuit draining the stored energy. These capacitors are used to retain saved parameters and memory learned by the on-board computer and thus resetting all adaptations.
Transmission fluid would not prevent the vehicle from starting. You mentioned it would not move under its own power. I brought it up as a basic check or assessment of your vehicle. Coolant can cause electrical issues it just depends on where it got because some circuits are low voltage and low amperage that coolant could disturb the signal on that particular circuit.
Is there any coolant in any of the spark plug tubes? This will cause the spark from the coils to short to ground rather than going through the spark plug. These tube must be free of oil and/or coolant/water.
The engine will should down after it recognized the sensors and components are disconnected when you did your compression test without the intake/plenum & throttle body. So that is why it ran & then shut down.
If I didn't overheat and the compression is good on all cylinders. There is something else causing the engine to run poorly. Did any wiring get damaged from the broken serpentine belt or ground strap?
