What to expect at the repair shop when your Mercury Mountaineer won't start

What will be the outcome of a no start diagnosis?

Correcting most no-start problems usually involves replacing the alternator, starter, or battery, cleaning connections, ignition system repairs, or fuel system repairs. Due to the wide variety of components that can possibly cause a no-start condition, repairing this issue could involve replacing a fuse, or replacing the engine, and repair procedures are on a case-by-case basis.

RepairPal Recommendations for a no start diagnosis

When a vehicle doesn't start it can be for many reasons. To avoid replacing unneeded parts we recommend having a professional perform a diagnostic test to identify the root cause of the problem.

What to look out for with a no start diagnosis

Diagnosing modern automotive systems without proper knowledge and training can be frustratingly difficult, but without proper technique the diagnosis will only be reached through changing parts on a hunch. Automotive systems, especially in the last 10 years, have become extremely advanced, and most vehicles have a communication network that allows all of the systems to communicate. This is a blessing for the trained technician, and a curse for the DIYer who would rather save money on the repair.
