I have a 2002 wangler sport , turn key nothing happens , the battery is good, change ignition switch and ignition pin still nothing, if I wiggle the key can get all Instrument to work with radio but as soon turn key to start goes dead again

It goes dead as in absolutely everything shuts off? do your hazards work when the jeep is "dead"? Or brake lights? Have you checked any fuses under the hood? Check for power at the main 40amp fuses, 4 or 5 of them in there. Check that you have a good ground, terminals are not cracked and are tight. Check that the connection to the PDC under the hood is good.
