With some limits I have to disagree with that when troubleshooting. By that
logic, if there is a problem, replace all parts that could cause the problem
(let's assume five or six), start vehicle, and if now running okay charge
for all the parts and never know which one was the problem.  No customer is
going to be happy with that plus the problem wasn't defined even though
cured.  The customer is going to tolerate some amount of time to diagnose
but is going to be very unhappy with paying for parts that didn't need
replacing.
