I had a similar issue with my jeep. There was a valve spring that snapped in half. Run a diagnostic to see which cylinder is misfiring and check the spark plug for any dings/dents. We found damage on our spark plug which told us something inside was busted. It was a lot of frustrating work but she purrs like a kitten now.

The switch at the fixture may have been turned on inadvertently. Door switch(es) could be defective.

Inside the PCM is a transistor that turns on an off that coil . Builds magnetic field when powered up , then when power shuts off the field collapses inducing higher voltage in the secondary side of the coil . This creates the spark to the spark plug. The PCM use a input from the crankshaft position sensor to control the coils . IF the coil is good an wires an plug good , transistor is side the PCM maybe fried . Testing the coil driver (transistor) is what you need to do to determine if the PCM needs replacing , can't be the crank sensor or none of the coils would fire . https://www.youtube.com/watch?v=8FnYllf5D9E&t=13s

Hi. Have you tested the neutral safety switch? With the gear selector in Neutral, try to start the engine. Have you looked at all the fuses? Don't just look at the fuse for the starter. Next. Test the starter. Make sure the starter is well grounded to the engine block and that the main power cable is tight and free of corrosion and damage. A second person is needed. With a friend in the car, and a test light hooked up to ground. Have your friend hold the key in the start position. At the same time you will have the test light making good contact with the starter trigger terminal. Does the light eliminate while the key is in the start position? If it does then the starter is bad. If not, there is something preventing the starter from powering up. Examples: Starter relay, antitheft system, ignition switch, fuses, relays, modules and wiring. You will need to take your time and test and examine as much as you can. Sometimes the problem is a quick and easy fix but sometimes it takes a while to figure out. Let me know how things are going. Please write back with updates or questions. Good Luck.

To do this you first have to remove the door panel on the inside while mkeing sure that the window is rolled all the way up then look on the inside of the door in the area of the outer door handel and you should see 2 taps and a couple metal rods, connected to the outer door handle, first disconnect the rods then remove the taps pull the door handle out from the outside and then reinstall in reverse!

These seem unrelated. For the brakes, check continuity through the turn signal switch. For the panel, check the dimmer on the headlight switch.
