Your dad showed her the coil or distributor wire connections. Like the one answer said start from the spark plug wires, (4-wires evenly spaced on the side and top part of the engine) follow those wires to a small round cap, (the distributor) the wires coming out of it is a plug in type connector, It that one unplugged? If not look at the center wire in between all four of the plug wires on the distributor, (coil wire) follow that center wire to a small black plastic looking box, (about 3 by 3") there is a plug in connector there check that one. It should be one of the two connectors that is unplugged OR maybe even pull out slightly to look unplugged but is laying close to each other so you may not see it right away. I also did this to my 17 year old when he got bad grades in school so I made him take the bus, I know the bus bites, his grades got real good after that. What are you in for? Good luck Girl! check at these two spots, it is a 20-second job to do this disable it. There is also a IGN fuse they can pull, look for a black plastic box under the hood, open the cover, look under the cover for a IGN ( ignition )fuse location, if they took that one out then you will need one to re-install to get it going.
Ps if you do drive it and they don`t see you doing it, when you get home just unplug it again.
