Problem:
Car turns over and will not start.

History:
Car has been sitting for 6 months. Battery was dead 2 days ago. Battery was new June of 2022. Fully charged battery with positive terminal disconnected on 2A charger. Today it says full charge. Removed charger, connected battery cable, saw a spark and alarm went off. Key fob would not turn off alarm. Climbed inside and tried to start it. Key would not turn at first. After waiting about 30 minutes with key in ignition, I removed the key and the lock and unlock started working. So I did that a couple of times. Noticed the tow red led blinking on the dash.. hit that button. Then I tried to start it again and this time ignition lock, unlocked allowing me to turn the key. The key turned all the way to engage the starter but no start. The starter cranked quickly letting me know that the battery indeed has plenty of power. Fuel is 6 months old. Car ran last 6 months ago when parked just fine. No water in central vacuum area as I replaced that unit and keys 5 years ago and added a drain hole at that time. I have tried removing fuses 26 and 27, just trying things that said computer on the fuse card paper. I think the car is in a anti-theft scenario? It has been a great car and starts strong usually every time. 4 years ago I was getting limp mode due to a throttle pedal position sensor.. that was easy to reprogram and has worked well since. I have tried applying the brake pedal while cranking. Does the drivers door need to be closed? E brake is set. It will allow me to put the car into neutral when key has been turned but I did not try to crank it from there yet. I do not own a code reader, This scenario has happened to me in the past but it's been so long ago I can't remember what to do, but once I did it, it started up immediately last time. I don't think I'm hearing the 1 second fuel pump sound with key off/on either at the moment.

any ideas?

Greatly Appreciated
