i have an 06 ram, about 120k miles. went to walmart after work yesterday morning, when i left work the truck wouldn't start until about the 4th or 5th attempt. no buzzing of the starter, turn the key over and nothing. have full power, lights, dash lights, radio, etc... so got it started (it's done this once before a couple months back) ran to walmart quick to grab a jug of supertech, and came out and same problem. this time i was in the parking lot for a half hour. crawled under, tapped on the starter over and over... nothing. tried numberous times. about 25 minutes or so of sitting there i decided to try to turn the key over one last time and it fired up like nothing was wrong. now given the taps on the starter had no effect, and it didn't seem like it was "sending power" to the starter to attempt to start, would you guys look at the ignition switch first?
