Q: Q: Car won't start

asked by on

My car is not starting.

Hello. When a car won’t start, start with the basics: If the vehicle has power, then power to the starter motor must be checked, and voltage drops performed. The larger wire at the starter motor should have 12v at all times, and the smaller wire should have 12v in the Start position. If voltage is good, the a voltage drop should be performed between the battery positive, and the same two wires in the Start position. If the reading is less than 0.5v, the wiring is good, and the starter has failed. If there is a lack of 12v at either wire, then the circuit must be checked to find the open circuit. The starter motor is mounted on the underside of the vehicle, so you may need the aid of a mechanic to jack-up your car, and perform electrical tests to properly diagnose your non-starting issue.
