Question about Goodman Heating & Cooling
If this a system on a home. You should have 230v to the compressor. If this is a window unit rated for 120v and the compressor is not hot then you mostly have open windings in the compressor and the compressor is dead.

Make sure ALL moisture and noncondensables are evacuated while the system is down.I would have the line flushed to remove all remnants of burnout.Actually with the age of the unit and amount that needs repaired I would change the unit out to a 410a system and start over.

SOURCE: COMPRESSOR NOT RUNNING, HOT
The high side/low side pressure equalization you describe is normal for a compressor sitting idle.
If you have an ohm meter you can check the compressor windings for opens and shorts. If your compressor is 3 phase as you state (this would be very unusual for a residential unit) you should have continuity across all 3 phases and no continuity to ground. Take the compressor out of the circuit before you check.
If the compressor does have crankcase heat, it should have been left on for at least 24 hours before starting the unit. Another cause for failure could be overcharging which could have resulted in refrigerant slugging back to the compressor.
Does the unit have any low or high pressure control safeties? If so, check them too - some have resets. You said the condenser fan ran so it's not likely the breaker blew, but check anyway and also check to make sure you have available power on all 3 phases.

SOURCE: p8 eroor code
P8 error is abnormal pipe temperature indoor. If you are running it on heating P8 error will appear because the disc pressure is too high. It could be overcharged.

SOURCE: compressor not turning on
is the compressor actually turning over ?? if not check the contactor, or capacitor is actually ok...
if it does turn over, are the stop valves open ??

It could be any of a number of things: be sure and check the fuses and relays under the hood in that fuse panel , also the mail switch inside ,, you can jumper those contacts to see if it's the switch , here are some other ideas
