does anyone know how long it takes to diagnose if i need a new fuel pump? my car has been at the shop for two days and when i call they say they are looking into it.
That’s not the question to the mechanic. That’s a possible DIAGNOSIS revealed by diagnostics. The question for the mechanic is, “What IS the problem, and what diagnostic test do I perform to REACH a diagnosis?”. After that, “What is the fix?”.// When you take the car to the shop, you can help whole process if you give a thorough account of the symptoms to the mechanic, or service person. Where do you think doctors, like Dr. House, learned there troubleshooting techniques? From mechanics, of course.
