So here's an update.

I got all my electronics working. The problem was a wire with two paddles on the ends were used in place of a fuse, and the wire was broken. As long as it is pressed firmly down, it works perfectly.

Which brings me to the problems, I know my starter is locked up. But it also appears as if the fuel pump is messed too.

So yeah, money money money.

Wow this whole thread got so off topic and the OP did not get much of help.

Anyways, first off if the wire you are talking about is in the fuse panel under the hood that is how it is, they put a fuseable link wire in instead of a fuse, I don't know why seems like a bad idea. Anyways, the horn flashing and the horn going off is the alarm activating, on these cars they have a immobilizer alarm system built in. So if the alarm is activated, even if it turns off after the 2 mins of being on, it will shut off most of the systems of the car including the fuel pump and the starter. Sometimes when a battery is disconnected for a long time the alarm gets tripped hooking up power again.

Now with all that said your problem is the alarm is going off, you need to reset the alarm. To do this close the hood, hatch and both doors, lock the passenger door then the driver door with the key. The red light on the dash should come on solid. Wait for 20 seconds till the light starts to flash. Once its flashing unlock the driver door with the key. This will turn the alarm off which will allow the circuit opening relay to start working and give power to all the systems in the car. Now if you unlock the door with the key and the alarm turns back on or if the alarm does not go out when you lock the doors with the key that means you have a bad door lock sense switch which is attached to the back of the lock cyl in the door. It is a round thing with 2 wires coming out of it.

One problem you have is if the fuseable link wire was blown that probably means someone hooked up the battery backwards. So you may have other fuses blown, check the efi fuse in the driver kick panel that is one that usually goes when someone puts a battery in backwards along with some others.

GL on getting it working. I will be around now and then to hopefully help you fix it all if you have not all ready.

You will find that the parts are not cheap for this car.... I agree with META, it sounds like the alarm has you messed up. Electrical problems usally take more patience than money. Welcome to the club and we will do our best to help.
