Similar thing is going on with my 2000 SSEI ..CID says my rear left door is open, nothing is functioning in the back, locks windows, I replaced the left rear doors

Open the left front door and between the 2 hinges, you can see where are the electrical wires see if any wires are open circuit by pulling on each wire. You will find your problems there. Hope it helps.

I think you have a shifter cable problem. Engine off. Put the shifter into gear back and forth if under the hood at transmission cable if it moves. There is an adjusting system on the cable could be stripped or not lock.(It pop up then free cable action). Hope it helps.

Car won't start. Sounds like the engine flooded. Not the starter. Also loses power going uphill and when accelerating.

Check Engine Light flashing when accelerating ,severe engine misfire . Something in the ignition system is breaking down under a load . If the starter engages an spins the engine when you turn the key to start an it doesn't start an run , it has no spark or fuel pressure . If you don't know this or how to diagnose .suggest you take your vehicle to a qualified repair shop . Pull two plug wires off the top of the same coil an crank the engine , if you do not see a spark jump from one coil tower to the other you have an ignition system problem . ignition module or crankshaft position sensor Flashing check engine light CarMD
