2000 Chrysler LHS

If it's a rather loud clunk, suspect solenoid contacts in the starter motor. Very common problem with a cheap fix. The contacts are $20.00 for the pair. Most people don't know how easy they are to replace so they just replace the entire starter motor.

By now you've probably found that if you try it enough times, it will eventually crank. It will get progressively worse, but for now, it will usually start if you cycle the key enough times.
