Ray 3/22/2011Sounds like the ignition switch is bad.
Pepe 3/31/2014You can easily find a diagram that shows you how to test and replace the ignition switch, there may be a loose connection also but most likely you switch is bad.
HouseCallAuto 3/31/20141. Test the ignition switch by locating the Brown connector, in the driver's fuse box, just above the fuses. Locate the Black/Yellow (BLK/YEL) wire in the Brown connector. That wire should have battery voltage in the start and run position.
2. If the BLK/YEL wire does not have battery voltage in the run position, jump the White (WHT) in the Brown connector to the BLK/YEL wire, and if the vehicle keeps running, the ignition switch has failed.
