Great write ups here.
Over the weekend I replaced all of the burned out bulbs with new LED's in my '98, removed all of the center console components, replaced the PS lower dash speaker, and removed the front passenger seat so that I could do a deep clean.
After all of this, my engine would not turn over. Lights and stereo worked, windows were slow moving when I rolled them up, and there was a clicking sound when I turned the key. My battery seemed dead.
So, I tried jumping it to no avail.
I returned and replaced my battery b/c the shop said it was only putting out 40 amps. Again, it would not turn over even w/ the new battery.(no more clicking tho) My headlights and interior lights started flashing like they do when the factory alarm starts misbehaving. I tried pressing and holding the little red button and starting. ( i do not have a working remote) No result. I disassembled the cluster to make sure the alarm button wasn't damaged. It looks fine, but I have noticed that it doesn't light up under any circumstance now.
I think my next step is to follow the alarm removal directions found here:

I have always hated the factory alarm and it seems like now is the time to rip it out.
I have not replaced the PS front seat. Is there any reason to believe this would prevent starting? Is there any reason that replacing all of the LED's, replacing a speaker, or removing the seat would cause my battery to suddenly lose charge? I was starting and stopping the engine while I did the LED swap and was pretty surprised when I had a dead battery considering LED's are supposed to draw less.
