1984 no start issue!!
 

ive had the car for about a month now and since i got it ive been having occasional random problems with it starting! even after just driving it i would get back into it within 5 minutes and go to fire it up, nothing. no crank even. let it sit for a few hours, starts right up. after driving it to work a couple days ago, i shut it off and got out of the car and hit the lock button on the factory remote, nothing happened. no flashing lights on outside of car or anything. went to open the door to push electric lock button on the inside, still nothing. interior lights didnt even come on. went to turn the key, absolutely nothing happened. the car had ZERO electricity at all! i disconnected the battery for 10 minutes and after that it still did nothing...let it sat for a few hours, it fired right up and it acted like nothing ever happened. also, the starter relay behind the DIC switches will sometimes click when i open the doors and even for a while after the car is running. not sure if these issues are related or not.

i figure its for sure something to do with the factory alarm system. the lock cylinders do not work on either door so i cant reset the alarm or anything with the door key. can i simply bypass the starter relay behind the dash or remove the main alarm system fuse behind the dash to fix this?
i am fairly mechanically inclined but electrical has me confused. any help is greatly appreciated!
