Ignition switch? or other . . .
 

Got 2004 XC90, switch on, dash on etc., turn key, cranks up, next time might turn key 12 times before starter engages and cranks, next time turn key over and over, then will turn over, not crank... keep turning over and over, and ignition switches on and lets it crank. Do I have a bad ignition switch, or bad computer, or any body's guess??
