The car in question is a 1990 Chevy Lumina V6, automatic transmission. About once a week, when I turn the key nothing happens. No click, no starter grinding, nothing. When I move the gear shift from park over to neutral and back and try again, it starts up right away.
I am not an expert, but as far as I can tell, if it was a battery problem the car wouldn’t start every time after I moved the gearshift. Ditto for wiring and solenoid issues. If it was the starter, I’d hear the solenoid. If it was something after that, I’d hear the starter.
Logic tells me it has something to do with the car needing to be in park or neutral before the key’s turned, but my owner’s manual, Auto Repair for Dummies, teh intarwebs, and a Haynes repair manual have all so far failed to turn up a cause, let alone a solution.
