There could be a fusible link under the hood off the starter relay that is burnt out.

I think I have found the problem. When I wiggle the ignition switch the turn signals and radio go on and off so I feel the issue is in the ignition switch. From what I understand the actual electronics for the switch are at the base of the sterring column behind the lower dash panel and is connected by a rod that may need adjusting.

Check your backup light circuit at the trans.If this is a manual trans it will be a seperate switch if automatic it should be in with the neutral saftey switch.Sometimes on a automatic the switch is adjustable and may just out of adjustment.Check engine light have it scanned and turn off light by clearing code at your local Autozone or pepboys
