A starting system diagnostic is the process of figuring out why your engine won't "catch" and run. There are two main scenarios: either the engine won't crank at all (usually a battery or starter motor issue), or the engine cranks but won't start (the starter is spinning the engine, but there’s no "fire"). In South Africa, common culprits range from failing fuel pumps—often stressed by running on low tanks—to ignition components that have perished in the engine bay's high heat. This inspection is designed to isolate whether the "no-start" is caused by a lack of fuel, a lack of spark, or a mechanical timing failure.
If the engine cranks, but the car doesn’t start:
A top-rated mobile mechanic will come to your home or office to determine the source and cause of your car’s failure to start, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.
The mechanic will check the ignition system, fuel system, and charging system, and then look for any mechanical damage. The mechanic may also try an alternative fuel source, like a quick shot of brake or carburetor cleaner into the throttle body, or a quick shot of liquid fuel via a vacuum line. If the car starts momentarily and then dies, that indicates that you have a fuel delivery issue.
It goes without saying that a non-starting car is an important issue to address. Do not ignore or abandon the car if it’s not starting; this is an issue that should be dealt with promptly. Book a mechanic to perform a thorough inspection as soon as possible.
