My jeep will not crank.
The first thing to check would have to be the battery since the battery is the heart of the system. Once the battery is known to be ok then the starter is checked to make sure it is getting power from the battery and has a good ground. Then, the starter is checked for proper power from the ignition switch. If no power is coming from the ignition switch, it may be the shift select switch open circuit. I recommend these checks be done by a qualified technician.
