How many miles on the vehicle?

Customer: replied 1 year ago.
70K, but has been all but dormant for the past 4 years. Also the tach never homes (even with power off), and is erratic. Sometimes will not crank as if starter cut relay is not energized. I have Alldatadiy and it seems everything problematic passes through a CPU #2.
