Why wont my jeep start

Susan Luntsford, you did not tell us if it is stock or if it is a mod jeep. Engine Size and mods are important since it does make a difference. If you have no power to the coil, check your ignition switch. Make sure the switch close the circuit to the ignition coil. Check the wiring from the positive terminal of the battery to the switch, make sure it is connected and not shortened out. If it worked before, but stopped working since you replaced the parts, double check your work.
