No Start Diagnosis
What is a "no start" condition?

When you turn the key, but the engine does not start, the vehicle is in need of a no-start diagnosis. This diagnostic spectrum focuses on understanding what is preventing the engine from starting, how is it preventing the engine from starting, and the cause.

How does a no start happen?

Generally, a "no-start" vehicle will either fail to crank, or fail to start while cranking. When this occurs, the technician must comb through the vehicle to find the issue, usually using diagnostic scanning tools. No-start conditions can arise from many locations on the vehicle, including the engine, obviously, but also the transmission, grounding wires in any part of the vehicle, the battery or alternator, or even a 12-volt car charger plug. Finding and identifying the problem can be a long and tedious process, but trained technicians typically handle diagnostic work in as short a time as possible.

What symptoms are related to a no start?

As discussed, many things can trigger a no-start condition, so there may be associated symptoms. If there is an electrical problem followed by a no-start condition, there may be the sound of a fuse popping, brief smell of burning, or sounds of charring. Vehicles that will not start because of a faulty electronic fuel pump, the fuel pump noise is noticeably absent when the key is first turned on, or when the door is first opened before driving. Noting any symptoms that occurred before problems can greatly diminish the time needed for diagnostics.

Can I drive with a no start condition?

Generally, the vehicle can be driven if it can be started, however, if the vehicle cannot be started, of course, it must be towed to a repair facility. If the vehicle is making a burning smell, smoking or abnormal sounds are heard from any component, the battery should be immediately disconnected, and the vehicle should be sent to a professional technician.

How often do no starts happen?

Most vehicles will fail to start sometime, some more or less than others. Most commonly, vehicles fail to start due to an issue in the starting and charging system, such as a bad battery, bad alternator, bad battery cable, or bad starter. These are found very quickly, as a starting and charging system tester will be connected, and the starter, alternator, battery, and all connectors will be tested by the machine, allowing the technician to understand exactly what is happening in the starting and charging system. Unfortunately, there is no way to estimate when a no-start condition may occur, but proper maintenance and inspections can help prevent their occurrence by catching problems early.

No Start Diagnosis Repair Information

How is a no start diagnosis performed?

Most no-start diagnostics work begins with attempting to start the vehicle, and observing the result. The vehicle may do nothing, start, attempt to start, or click. The dash lights should dim when the key is turned to start, the vehicle should come to life when 'on' or 'run' is selected, and the fuel pump should be heard at some point before the key is turned to start the engine. The technician will listen for these clues, and most of the time, the problem will be associated with one of those issues. In most occurrences, no start problems are solved when the starting and charging system is tested. The starting and charging system is tested automatically, by machine, controlled by a trained technician. This includes the battery, alternator, starter, battery cables, and ignition switch. If this system functions properly, the technician will connect to the vehicle with a computer scanning device, and read OBD trouble codes, as well as test components, or read sensor inputs. From there, the technician must rely on formal training to interpret data, conduct further diagnostics, and find the fault.

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.

Can I perform no start diagnosis myself?

Most handy people can easily learn diagnostic steps, and diagnose their starting and charging system, which is the root of most starting issues. However, there is a limit on the amount of good that an untrained person can accomplish, especially if tools on hand are limited, as is the case for diagnostic equipment on most occasions. The task of diagnostics should be left to a professional technician once all knowledge and tooling resources are dissolved, as damage may occur without excellent knowledge, skill, and tooling.
