No start or crank

First, turn on headlamps. If they're bright, and don't dim when the key is turned, the battery is o.k. listen for a click. if you hear any click, it's probably the starter. No click - try turning the key with the shifter in "N" Nothing - back to Park. At this point, it could be anything; ignition switch, neutral safety switch, open wiring, etc. If you want to pursue it yourself, you have to get a wiring diagram and test point to point. It can't be diagnosed on line.
