battery went dead I jumped battery, now only the alarm comes on when turning the ignition

I have a 1997 Ford Explorer and the battery went dead. I jumped battery, now only the alarm comes on when turning the ignition. alarm goes off, but engine won't even turn.

Answer:

Buy a new battery or charge the one you have. Remove old battery or disconnect the one you have. Turn ignition key to the "on" position and leave it there while you connect the new battery or charged battery. Start car.


With the key being on when you connect the battery the computer knows its OK to start.
