Will not start there is no juice going from the battery to the engine at all the lights will not turn on or the horn won't blow nothing works at all

Even though all your other electrical bits are working it could be that your battery doesn't have enough juice to crank the engine. It doesn't take much power to run the radio, lights, etc, but cranking the engine requires the battery to have a very strong charge. If your battery is more than 5 years old, that's very likely the issue. I'd start there. Also, be sure to check the battery terminals and ground for corrosion and clean if necessary. If replacing the battery doesn't solve the problem it could be the starter solenoid or a loose electrical connection somewhere.

You could have blown the main fuse while doing the jump start. Also check the fusible link on the power battery cable.

if the lights come on you'r getting juice from the batt,if they go out when you crank the motor over batt is bad or you have bad batt connections

Most likeley the horn switch itself in the steering wheel. These are nothing more than two metal strips seperated by a thin piece of plastic. As the plastic ages and or wears, they make contact and the horn will blow at any time, sometimes just by expansion from heat or shrinkage from cold. They can be expensive if it involves the air bag depending on the different models.

Sounds like your battery is just too dead, has enough juice to light up the system for a minute but cranking drains it and if it wont charge then deff fried, you could try removing the battery and starting the car with cables to confirm the starter still works. If a bettery is too dead then when you are jumping it, it takes to much of the power just trying to get through the battery.

blow horn, see if lights in dash light up then turn key all the way like you start car if lights go out and no engine clicks are anything u hhave starter probelms replace it

I would check to see if this is a relay problem for the horn. Remove the relay for the horn and see if you can swap it with another to confirm it is bad. If with another relay it doesn't stay on you no it was just a relay so go get a new one. The only other thing could be a security issue and when you discharged the power by unhooking battery the vehicle is acting like it has been broken into. But i would say it's a relay problem. Good Luck.

The security system does not disable the starter, it only disables fuel to the engine. In the fuse block under the hood, locate the STARTER relay. Place your hand on this relay and see if it clicks while someone else turns the key to start...if the relay is ok then the starter itself is faulty. Good luck, i hope this helps.

You can do this for now so its not driving you crazy, then get it fixed.
If your car horn starts blaring and seems to be "stuck" (it won't stop blowing), you could be in for a few embarrassing moments. There's nothing quite like the stares and expressive hand gestures you can draw as your horn takes on a life of its own. There are a couple of things you can do to get the horn to stop.
If it got stuck when you pressed on the horn switch on the steering wheel, it could be because the switch itself is stuck. Press the horn switch again, or tap it a few times to see if it gets unstuck.
Turn off the engine and look for your fuse box. Look through the circuit descriptions and see if you can find one for the horn. If you can, pull the fuse. This should silence the horn immediately.
If you can't find the fuse box, can't remove the fuse, or the horn doesn't turn off, then you need to resort to more drastic measures. Open the hood of the car and try to locate the horn. If the rear of the horn is visible, you might be able to see the wires that lead to it. Disconnect the wires. If you can't disconnect them, then cut one of the wires. If you cut the wire, wrap the resulting two ends of the wire with tape so that they can't short out your electrical system.
You could disconnect the main wires that run to your battery. You shouldn't cut these but should disconnect them using a wrench. This might "reset" the horn. Hook the wires back up and if the horn doesn't turn back on, you should go directly to an auto repair shop to figure out what is going on. If the horn does turn back on, you'll need to locate and disconnect (or cut) the wires to the horn as previously described. Then, go to the auto repair shop and let them replace the horn for you.

replace your battery. Even when a battery is dead it will still have enough juice to operate smal things like the horn and radio, but not enough juice to start the car. If the battery is dead you should still be able to jump start it and take it to autozone and they can check it along with the alternator at the same time.
