Does the OBD II read any codes ? The key should only allow power to everything when in "Accessories or Run" position. Check the "key" switch and the Ignition shift lock module. If you look underneath the dash board, just below the dash/column mount and above the floorboard/column mount, you will see an electrical switch (top side of column) that is activated by the key switch "rod" when turned to "Run" or "Accessories". There will be two sets of wires connected to this switch which allows operation of the vehicle. I would say one of these switches is broken and out of alignment causing your issue.

should i get a jump before looking at this?

You need the battery charged enough to run the test, so either "jump it" or put a "charger" on it until it has the power. YOU DO NOT NEED to start the car to run the test in "Run" the key just needs to be in that "position" on the column switch (Key On, Engine Off).

I have a 98 Eldorado ETC that has similar problems I believe that I had narrowed it down to the same switch. I would like to know what contacts are made in each key position for further troubleshooting. Don't go running out and try to buy a new switch because they no longer make them. I haven't been able to find even an aftermarket switch. I guess I'll roll the dice and go to a salvage yard. Any advice ill be appreciated.
