So I was trying to test one of those Bluetooth OBD2 scanners/adapters on my 2004 AP2. I plugged it in next to the console on the driver's side, turned the key one click, my dash lights turned on and the lights on the adapter turned on, and I tried to connect via Bluetooth on my phone. It couldn't find the adapter in range. So then I turned the key all the way, held the clutch in, and pressed the red starter button (with the OBD2 still plugged in). The lights on the dash suddenly went off with a somewhat quiet "pop" sound, and that was it. Now if I put the key in the ignition the car will beep repeatedly as long as the door is open. With the door closed, inserting the key does nothing. Also, when I press the unlock/lock buttons on the key, I can hear the doors trying to unlock but it seems they don't have enough juice to actually flip the locks. Trunk also won't open, headlights won't turn on, etc.

Could the OBD2 adapter have shorted something? I did have the starter replaced about 8 months ago.

Update #1:

Checked the following fuses and they all appeared to be fine:

ACG
Ignition Coil
Engine Start
Starter Signal

Update #2:

Tried to jump start using my Civic. Let the engine rev at 2000rpm for almost 10 minutes. This is what happened:

Dash turns on, headlights work, but engine will not turn over. Could this be a shorted battery, or a bad starter?

well it's reacting just like a dead battery
my doors/trunk worked still when my battery was semi-dead

it starts almost immediately when jumping with the civic, right?

sound like your battery is drained and you have no cranking amps left. i would do a battery test. your car is cranking so you can rule out the starter.

Considering I don't have a multimeter or a trickle charger, which would make more sense to try first? Will O'Reilly usually test your battery for free if you bring it in?

tkeyyy

depends on if they have nothing more to do or if they're not lazy. the one by my place does it for free cause they're nice people

You can do tests on batteries only if they are fully charged. Your batteries sounds like they are drained. Try jumping it first and drive it around for about 30 mins to charge it up a bit and then see if it does anything. If it fixed the problem, I recommend doing that for about 2 to 3 days and then bring it in for a battery load test.

I tried jumping it a few times already to no avail. So should I even bother bringing the battery in to O'Reilly for a test?

It's not your battery.

Sounds like starter fluid might be little low.

Zygrene

But a little while after trying to jump start it, all the lights/electronics stopped working again. That suggests the battery ran out of juice again.

Did you check your big fuses?

which scanner do you have and what does it look like? If you connected certain pins on the obd scanner port (by way of your scanner), you may have damaged your ECU.

Edit: just re-read your charging method. Leave your civic running (with jumper cables attached) while you try to start your s2000 and see if it'll start.
