See my prior video of my Bonne. Rpm and mph don’t sweep. Turn head lights and fog lights on and if that shuts the car off, then start moving cables and connections under back seat, both red and black. And check under hood near fuse box there. If you can get under the car, check where the red wire bends to go under the car, that is where breaks occur I. Tight bend radius.

Sorry for the delay - this Covid is putting a damper on everything.
OK guys, I am at my wits end...
Here is another video I just took tonight - I put the key in - turn it to the accessory position and this is what happens. You can hear the times I tried starting the car - it finally starter at the 2:30 mark.
There is NO power to start the car UNLESS the yellow SERVICE ENGINE SOON light comes on - if all of the other lights are on, or even if all the lights are on and the fan is blowing (which you can hear in the video) there will be absolutely NO power to start the car.
The ONLY way that power comes to start the car is if the yellow SERVICE ENGINE SOON light comes on.
Here is the video:
Here is another one I took tonight also:

Yes - they were fine.
I am getting power, the radio comes on, the headlights come on, the electric windows and door locks work fine, etc. - even when the yellow SERVICE ENGINE SOON light is not lit up yet - they all work fine the minute the key is turned to the accessory position.
However, until the yellow SERVICE ENGINE SOON light lights up (like in the video) - I can turn the key to start the car and I get ABSOLUTELY NOTHING - no cranking of the starter, no ticking, no nothing.
The yellow SERVICE ENGINE SOON light has to come on in order to get "power" to the "starter?" and then the car will crank (most of the time, sometimes takes longer to crank than others) and will start.

Maybe a relay facing the PCM?
Otherwise it seems like an electrical connection is bad or corroded or loose.
