On my 1998 dodge grane caravan, I drove 15 miles to a place, parked it for 6 hours. while parked it rained. when I got in the van to start it after sitting for 6 hours, it would not start. lights would come on, but not the odometer or gear indicator lights. starter would not turn over. had van towed home and van will still not start. the next morning the van started normally. could there have been enough accumulation of moisture to shut the vehicle down like that ?
