No ground wire on the starter. Its bolted right to the engine / transmission.
Based on the "no click" observation, there are two things that come to mind.
Starting with the '96 models, the neutral safety switch no longer simply grounds the starter relay. Instead, the neutral safety switch feeds a pin of the engine computer which grounds the starter relay. I did have one '96 Caravan still under warranty that would not crank due to the engine computer.
A more common problem is a broken cam on the end of the ignition switch cylinder. The switch will turn not quite far enough to get to the "crank" position.
Both problems can be detected at the starter relay socket under the hood. How did you check the relay? I get the impression you know what to do with a voltmeter or test light. Is that correct?
