I'm not there to hear, but kinda thinking it's gonna be pretty easy (for anyone who's been driving even a few years) to tell whether there's even a hint of the starter dragging lower than normal speed. What's your ear tell you that you have a concern there? During the time to arrange a scanner or program I'd be pointing the most attention toward replacing that wire and making the business case to do new IC and ICM (always together) since they're normal maint. items after about a 1/4 century. And if the car's never gotten distributor tune-up parts then it's WAY overdue.
